Combined 4 Bank Officer Preli 2019 Questions (31-60): Read the following questions carefully and choose the right answer.

(ম্যাথে সহযোগিতা করেছেন জুলফিকার আলী, সিনিয়র অফিসার, জনতা ব্যাংক লিমিটেড।)

- Three houses are available in a locality. Three persons apply for the houses. Each applies for one house without consulting others. The probability that all the three apply for the same house is

(A) 1/9

(B) 5/9

(C) 8/9

(D) 4/9

Answer: (A) 1/9

Exp:

One person can select one house out of 3= ^{3}C_{1} ways =3.

Hence, three persons can select one house out of 3 in 3 × 3 × 3 =27

So, probability that all three apply for the same house is = 3/27 = 1/9

- If the perimeter of a certain rectangle is 76 m and its area is 360 m
^{2}, then what is the length of its shortest side?

(A) 13

(B) 15

(C) 18

(D) 10

Answer: (C) 18

Exp:

2(l+b)=76

Or, (l+b)= 38

Or, l = 38-b —–(1)

lb=360 —-(2)

From (2)

(38 – b)b = 360

Or, 38b – b^{2} = 360

Or, b^{2} – 38b + 360 = 0

Or, (b – 20)(b – 18) = 0

So, b = 20 or b = 18

When b = 20, l = 18 and when b = 18, l = 20.

Thus, the shorter side is 18.

- The simple interest received on a sum of money at the end of 10 years is two times of the principal. At the same rate of interest, what would be the ratio of principal and compound interest received at the end of two years?

(A) 25: 11

(B) 20:11

(C) 20:9

(D) None of these

Answer: (A) 25: 11

Exp:

Let,

Principal = x

So,

2x = x x 10 x r/100

Or, r = 20%

Again, Let,

Principal = 100

So,

C = 100(1 + 20/100)^{2}

= 144

Interest = 144 – 100 = 44

Required ratio = 100:44 = 25:11

- A student is to answer 10 out of 13 questions in an examination such that he must choose at least 4 from the first five questions. The number of choices available to him is

(A) 140

(B) 196

(C) 280

(D) 346

Answer: (B) 196

Exp:

If the student answers 4 questions from the first five questions he can choose 6 questions from the remaining 8 questions. Therefore number of combinations will be

=^{5}C_{4}×^{8}C_{6}=140

If the student answers 5 questions from the first five questions he can choose 5 questions from the remaining 8 questions; which will be

=^{5}C_{5}×^{8}C_{5}=56

So, total number of choices= 140+56=196

- For what value of x is 8
^{2x-4}=16^{x}?

(A) 2

(B) 3

(C) 4

(D) 6

Answer: (D) 6

Exp:

8^{2x-4}=16^{x}

Or, 2^{3(2x-4)}=2^{4x}

Or, 6x-12 = 4x

Or, 2x = 12

Or, x = 6

- Three dice are thrown together. Find the probability of getting a total of at least 6?

(A) 103/108

(B) 103/208

(C) 103/216

(D) 36/103

Answer: (A) 103/108

Exp:

Total number of events=6 × 6 × 6=216

Let A be the event of getting a total of at least 6 and B denoted event of getting a total of less than 6 i.e.,3,4,5.

So,B={(1,1,1),(1,1,2),(1,2,1),(2,1,1),(1,1,3),(1,3,1),(3,1,1),(1,2,2),(2,1,2),(2,2,1)}

Favorable number of cases=10

So, P(B)=10/216

Or, P(A) = 1 – P(B) = 1 – (10/216) = 103/108

- In a college Rahim scored 80 marks out of 150 in History and 95 marks out of 120 in English. If he wants to score 70% marks in 3 subjects, find the minimum marks he should score in Geography out of 100.

(A) 70

(B) 55

(C) 76

(D) None of these

Answer: (D) None of these

Exp:

Total marks = 150+120+ 100 = 370

Marks obtained in 2 subjects = 80+95 = 175

Total marks to be obtained = 370 × 70% = 249

Marks needed in Geography = 249 – 175 = 74

- If x=1+√2 and y = 1-√2, find the value of (x
^{2}+y^{2}).

(A) 12

(B) 6

(C) 8

(D) 10

Answer: (B) 6

Exp:

x=1+√2

Or, x^{2} = (1+√2)^{2} = 1 + 2√2 + 2 = 3 + 2√2

y=1-√2

Or, y^{2} = (1-√2)^{2} = 1 – 2√2 + 2 = 3- 2√2

x^{2}+y^{2} = 3 + 2√2 + 3 – 2√2 = 6

- X can do a piece of work in 20 days and Y can do the 1/7th of the same work in 5 days. In how days together they can complete the 11/14th of the total work?

(A) 15 days

(B) 20 days

(C) 10 days

(D) 12 days

Answer: (C) 10 days

Exp:

Y can do in 1 day = 1/(7×5) = 1/35

X & Y together do in 1 day = 1/20 + 1/35 = 11/140

11/140 work is done in 1 day

So, 1 work is done in 140/11 day

So, 11/14 work is done in (11/14) × (140/11) = 10

- The circumference of the circle and the perimeter of the square is equal and the ratio between the diameter of the circle and the side of the square is 7:11. What is the area of the circle?

(A) 154 cm^{2}

(B) 160 cm^{2}

(C) 132 cm^{2}

(D) Can’t be determined

Answer: (D) Can’t be determined

Exp:

Let, the side of the square = 11x and

diameter of the circle = 7x

ATQ,

2π(7x/2) = 4×11x

Or, 2 × 22/7 × 7x/2 = 44x

x omits. So, it can’t be solved.

- The average weight of 17 students is 90 kg. If the weight of teacher is also included, then the average weight is increased by 200 grams. Find the weight of the teacher?

(A) 93.6 kg

(B) 94 kg

(C) 93.4 kg

(D) 94.6 kg

Answer: (A) 93.6 kg

Exp:

Total weight including teacher = 18×90.2 = 1623.6

Total weight of 17 students = 17 × 90 = 1530

So, weight of teacher = 1623.6 – 1530 = 93.6

- A train can cross another train of equal length coming from the opposite direction with the speed of 108 km/h in 3 minutes. The speed of the other train is 90 km/h. Find the length of the train.

(A) 5940 m

(B) 5490 m

(C) 4950 m

(D) 4590 m

Answer: (C) 4950 m

Exp:

Relative speed = 108 + 90 = 198 km/h = 198 ×(5/18) m/s

Distance covered in 3 minutes = 198 ×(5/18) × 3×60 = 9900 m

So, length of a train = 9900/2 = 4950m

- A can complete a piece of work in 12 days, A, B and C can complete the work in 6 days. Efficiency of B is 0.5 times the efficiency of A. In how many days C can complete the work alone?

(A) 24 days

(B) 10 days

(C) 16 days

(D) 12 days

Answer: (A) 24 days

Exp:

A can complete 1/12 work a day.

So, B can complete (1/2)x(1/12) = 1/24 work a day.

So, A+B can complete (1/12 + 1/24) = 1/8 work a day

A+B+C can complete 1/6 work a day.

So, C can complete (1/6 – 1/8) = 1/24 work a day.

So, C needs 24 days to complete.

- A shopkeeper sold an item at 20% profit and another item at 10% loss. If the cost price of both the items is same, find the overall profit percent.

(A) 7.55%

(B) 6.00%

(C) 5.00%

(D) 6.50%

Answer: (C) 5.00%

Exp:

Let, cost of each item = 100

At 20% profit, selling price = 120

At 10% loss, selling price = 90

Total selling price = 210

Total cost = 100+100 = 200

Profit = 210-200 = 10

Profit % = (10×100)/200 = 5%

- 8 males and 6 females can do a piece of work in 5 days. 5 males and 6 females can complete the same work in 7 days. How many days will a female take to do the job, if she works alone?

(A) 135 days

(B) 142 days

(C) 110 days

(D) 126 days

Answer: (D) 126 days

Exp:

8x + 6y = 1/5 —-(1)

5x + 6y = 1/7 —-(2)

(1)-(2),

3x = 2/35

Or, x = 2/105

From (2),

5 x 2/105 + 6y = 1/7

Or, y = 1/126

Days need = 126.

- A is 30% more efficient than B. How much time will they, working together, take to complete a job which A alone could have done in 23 days?

(A) 13 days

(B) 15 days

(C) 10 days

(D) None of these

Answer: (A) 13 days

Exp:

Ratio of times taken by A and B = 100 : 130 = 10 : 13.

Let, B takes x days to do the work.

Then, 10 : 13 :: 23 : x

Or, x = ( 23 × 13/10 )

Or, x = 299 /10

A’s 1 day’s work = 1/23

B’s 1 day’s work = 10/299

(A + B)’s 1 day’s work = ( 1/23 + 10/299 ) = 23/299 = 113 .

So, A and B together can complete the work in 13 days.

- The area of lawn is 460 m
^{2}. If the length is 15 percent more than the breadth of the rectangular field. What is the length of the field?

(A) 15 m

(B) 26 m

(C) 34.5 m

(D) None of these

Answer: (D) None of these

Exp:

Let, Breadth = x

So, length = x + 15% of x = 23x/20

ATQ,

23x/20 × x = 460

Or, x^{2} = 400

Or, x = 20

So, length = 23×20/20 = 23

- A boat can travel from point A to point B and return back to point A in 9 hours. Speed of the boat in still water is 8 km/h and the speed of the stream is 4 kmh. Find the distance between A and B.

(D) 45 km

Answer: (B) 27 km

Exp:

- A 10% monthly salary increase resulted in a tk. 9000 per year increase in salary for an employee. What was his monthly salary before the increase?

(A) Tk.5000

(B) Tk.9000

(C) Tk.7500

(D) Tk. 12000

Answer: (C) Tk.7500

Exp:

Yearly increase = 9000

Monthly increase = 9000/12 = 750

10% of salary = 750

So, 100% of salary = (750×100)/10 = 7500

- When a certain number is divided by 7, the remainder is 0, if the remainder is not 0 when the number is divided by 14, then the remainder must be

- A mixture of 20 kg of sprit and water contains 10% water. How much water must be added to this mixture to raise the percentage of water to 25%?

(A) 2

(B) 4

(C) 5

(D) 6

Answer: (B) 4

Exp:

In 1^{st} mixture, water = 10/100 × 20 = 2

Spirit = 20-2 = 18

In 2^{nd} mixture,

75 kg of spirit is contained in 100 kg mixture.

18 kg spirit is contained in 100/75 × 18 = 24 kg

So, water to be added = 24-20=4 kg

(C) 55 2/3

(D) 43 3/4

Answer: (D) 43 3/4

Exp:

= 7/16 × 100

= 43 3/4

- The average attendance of a college for the first three days of a week is 325 and first four days is 320. How many were present on the fourth day?

(A) 300

(B) 315

(C) 305

(D) 350

Answer: (C) 305

Exp:

Total attendance for first 3 days = 325×3 = 975

Total attendance for first 4 days = 320×4 = 1280

Present on the 4^{th} day = 1280-975 = 305

- Tk. 355 has been divided among A, B, C in such a way that A had Tk. 20 more than B and C had Tk.15 more than A. How much was C’s share?

(A) Tk. 135

(B) Tk. 100

(C) Tk. 120

(D) Tk. 150

Answer: (A) Tk. 135

Exp:

Let the share of A was x

A has 20 more than B.

So, Share of B was (x – 20)

And C had 15 more than A So, Share of C was (x + 15)

Now,

Share of (A + B + C) = 355

Or, x + x – 20 + x + 15 = 355

Or, 3x – 5 = 355

Or, 3x = 360

Or, x = 120

Now, Share of C was x + 15 = 120 + 15 = 135

- If 2 kg of metal, of which 1/3 is zinc and the rest is copper, be mixed with 3 kg of metal, of which ¼ is zinc and the rest is copper, then what will be the ratio of zinc to copper in the mixture?

(A) 13:42

(B) 19:43

(C) 15:42

(D) 17:43

Answer: (D) 17:43

Exp:

In 2 kg of metal,

Zinc : copper = 2×1/3 : 2×2/3 = 2/3 : 4/3

In 3 kg of metal,

Zinc : copper = 3×1/4 : 3×3/4 = 3/4 : 9/4

Now, new ratio = (28/3 + ¾)/(4/3 + 9/4) = 17/43

ATQ,

Cost price = 100/150 × 6000 = 4000

Selling price = 4000+ 500 = 4500

Required % = 1500/6000 × 100 = 25%

- Out of two numbers, 4 times the smaller one is less than 3 times the larger one by 5, If the sum of the numbers is larger than 6 times their differences by 6, find the two numbers.

(A) 55 and 58

(B) 23 and 28

(C) 59 and 43

(D) 65 and 67

Answer: (C) 59 and 43

Exp:

Let the two numbers be x(smaller) and y(larger) .

ATQ,

4x = 3y – 5

Or, 4x – 3y = – 5

Or, 3y – 4x = 5……. (1)

Again,

x + y = 6(y – x) + 6

Or, x + y = 6y – 6x + 6

Or, 7x – 5y = 6…….. (2)

Multiply equation 1 by 5 and equation 2 by 3 we get :

15y – 20x = 25

21x – 15y = 18

Adding the two :

x = 43

From (1),

3y – 4 × 43 = 5

Or, 3y – 172 = 5

Or, 3y = 177

Or, y = 177/3

Or, y = 59

- The sum of the squares of three numbers is 532 and the ratio of the first and the second as also of the second and the third is 3:2. Then the first number is

(A) 18

(B) 6

(C) 12

(D) 20

Answer: (A) 18

Exp:

let they are x,y,z.

so x^{2}+y^{2}+z^{2}=532.

Given,

x:y=3:2 and

y:z=3:2

then x:y:z=3×3:2×3:2×2=9:6:4

Now, numbers are 9a, 6a, 4a

So, (9a)^{2} + (6a)^{2} + (4a)^{2} = 532

Or, 81a^{2} + 36a^{2 }+ 16a^{2} = 532

Or, 133a^{2} = 533

Or, a^{2} = 4

Or, a = 2

So, the first number is = 9×2=18

- Pipe P can fill an empty tank in 4 hours but pipe Q can completely empty the same tank in 8 hours. Both the pipes were opened alternately after every two hours starting with pipe P then in how many hours, the tank was completely filled?

(A) 6 hours

- The average age of A, B and C is 30 years. If the difference between B’s age and A’s age is same as the difference between C’s age and B’s age. If D is 40 years older than B then what is the sum of the age of B and D?

(A) 130 years

(B) 60 years

(C) 75 years

(D) 100 years

Answer: (D) 100 years

Exp:

A+B+C = 30×3=90 —–(1)

ATQ,

B-A = C-B

Or, A+C = 2B

From (1),

B+2B = 90

Or, B = 30

D= B+40 = 30+40 = 70

So, B+D = 30+70 = 100
