## PKB Assistant Programmer Preli 2019 SECTION-C : GENERAL MATHEMATICS Questions (21-40): Read the following questions carefully:

- There are 15 boys and 10 girls in a class. If three students are selected at random, what is the probability that 1 girl and 2 boys are selected?

(A) 1/40

(B) 1/2

(C) 21/46

(D) 7/41

Ans: (C) 21/46

n(S) = Number ways of selecting 3 students out of 25 = 25C3 = 2300.

n(E)= (10C1 x 15C2) = 1050

P(E) = n(E)/n(s) = 1050/2300 = 21/46

- A man takes 3 hours 45 minutes to row a boat 22.5 km downstream of a river and 2 hours 30 minutes to cover a distance of 10 km up stream. Find the speed of the river current in km/hr.

(A) 1 km/hr

(B) 2 km/hr

(C) 3 km/hr

(D) 4 km/hr

Ans: (A) 1 km/hr

3 hours 45 minutes = 3.75 hr

2 hours 30 minutes = 2.5 hr

Speed upstream = 22.5 km / 3.75 h = 6 km/h

Speed downstream = 10 km / 2.5 h = 4 km/h

the speed of the river current = (6-4)/2 = 1 km/h

- A square is inscribed in a circle of diameter 2a and another square is circumscribing circle. The difference between the areas of outer and inner squares is –

(A) 4639.4

(B) 4769.6

(C) 4830.8

(D) None of these

Ans: (D) None of these

Cost price = (3362+2346)// = 2854

Selling price = 2854 × 120/100 = 3424.8

- A train 150 m long passes a pole in 15 seconds and crosses another train of the same length travelling in opposite direction in 8 seconds. The speed of the second train in (km/h) is –

(A) 60 km/hr

(B) 66 km/hr

(C) 99 km/hr

(D) 72 km/hr

Ans: (C) 99 km/hr

Speed of the first train = 150/15 = 10 m/s

Relative speed of two trains = (150+150)/8 = 37.5

Speed of the second train = (37.5 – 10)×18/5 = 99km/hr

- A jar contains white, red and green marbles in the ratios 2:3:5. Six more green marbles are added to the jars, and then the ratio becomes 2:3:7. How many white marbles are there in the jar?

(A) 6

(B) 7

(C) 8

(D) 9

Ans: (A) 6

Ratio of W : R : G= 2: 3:5।

If 6 Green is added, Ratio becomes W: R:G = 2: 3:7

Difference of ratio for 6 marbles = 7 – 5 = 2

For 1 ratio = 3 marbles

White marbles = 2×3 = 6

- An iron rod that weighs 24 kg is cut into two pieces so that one of these pieces weighs 16 kg and is 34 m long. If the weight of each piece is proportional to its length, how long is the other piece?

(A) 11 m

(B) 17 m

(C) 34 m

(D) 68 m

Ans: (A) 11 m

16 kg rod = 34m

24 kg rod = (34×24)/16 = 51m

Length of the other part is = 51-34 = 17m

- A train starts from city Y at 2 PM and travels towards city X at 75 km/hr. Another train starts from city X at 1 PM and travels towards Y at 60 km/hr. If the distance between these two cities is 330 km then at what time will they meet?

(A) 6:00 PM

(B) 5:30 PM

(C) 5:00 PM

(D) 4:00 PM

Ans: (D) 4:00 PM

Let,

They meet x hrs after 1PM.

So,

(Distance covered by first in x hrs) + [Distance covered by second in (x – 1) hrs] = 330

Or, 60x + 75(x-1) = 330

Or, 135x = 405

Or, x = 3

So, they will meet at (1+3)PM = 4 PM

- 100 kg of solution A is mixed with 60 kg of solution B. If solution A has tín and copper in the ratio 1:4 and solution B has lead and tin in the ratio 3:2, then what is the amount of tin in the new solution?

(A) 70 kg

(B) 36 kg

(C) 44 kg

(D) 56 kg

Ans: (C) 44 kg

In 100 kg of solution A,

Tin = 100×1/5 = 20

Copper = 100-20 = 80

In 60 kg of solution B,

Lead = 60 × 3/5 = 36

Tin = 60 – 36 = 24

In 160 kg of new solution,

Tin = 20+24 = 44

- On reducing the entry fee by 35% in a park, the number of people coming to the park increased by 40%, then the percent increase or decrease in the income from the entry fee is-

(A) 9% decrease

(B) 7% decrease

(C) 9% increase

(D) 5% decrease

Ans: (A) 9% decrease

Let the original entry fee be ‘a’ and number of people initially coming to the park be ‘b’.

Total income = a × b = ab

Now, reducing the entry fee by 35% in a park, the number of people coming to the park increased by 40%

∴ New entry fee = a – 35% of a = 0.65a

Number of people = b + 40% of b = 1.4 b

Total income = 0.65a × 1.4b = 0.91 ab

Decrease in income = ab – 0.91ab = 0.09ab

% decrease in income = 0.09ab×100%/ab = 9%

- One third of the faculty members of a department are female. Sixteen of the male teachers are unmarried, while 60% of them are married. The total number of faculty members in the department is –

(A) 72

(B) 60

(C) 30

(D) 90

Ans: (B) 60

Let,

Total number = x

Number of female = 1/3 of x = x/3

Number of male = x-x/3 = 2x/3

Married male = 60% of 2x/3 = 2x/5

ATQ,

2x/3 – 2x/5 = 16

Or, 4x/15 = 16

Or, x = 60

- Three numbers are added in pairs, the sums so obtained are 20, 27, and 23. What are those three numbers?

(A) 6,4, and 15

(B) 9, 11, and 14

(C) 10,8, and 17

(D) 8, 12, and 15

Ans: (D) 8, 12, and 15

Let, the number = a, b,c

So, a+b = 20

B+c = 27

C+a = 23

- A hall, 20 m long and 15 m broad, is surrounded by a verandah of uniform width of 2.5 m. The cost of flooring the verandah at Tk. 3.50 per square meter is-

(A) Tk. 600

(B) Tk. 800

(C) Tk. 700

(D) Tk 500

Ans: (C) Tk. 700

Area of verandah = [(25 x 20) -(20 x 15)] m^{2} = 200 m^{2}

∴ Cost of flooring = tk. (200 x 3.50) = tk. 700

- If the length of each of the sides of three square garden plots is increased by 50 percent, by what percent is the sum of the areas of the three plots increased?

(A) 125%

(B) 150%

(C) 200%

(D) 275%

Ans: (A) 125%

Let, the length of each side of the garden = 100

Area = 1002 = 10000

Area of 3 square = 3×10000 = 30000

50% increase of length = 100+100×50/100 = 150

Area = 1502 = 22500

Area of 3 square = 3×22500 = 67500

Increasing area = 67500-30000 =37500

Percentage = (37500×100)/30000=125%

- A driver of an auto rickshaw sees a lorry 60 meters ahead of him. After 30 seconds the lorry is 90 meters behind. If the speed of the auto rickshaw is 38 km/h, then what is the speed of the lorry?

(A) 23 km/h

(B) 20 km/h

(C) 25 km/h

(D) 18 km/h

Ans: (B) 20 km/h

Relative speed = Total distance/ Total time = (60 + 90)/30 = 5 m/s

∴ 5 m/s = 5 × 18/5 = 18 kmph

Now relative speed = speed of auto rickshaw – speed of lorry

or, 18 = 38 – speed of lorry

∴ Speed of lorry = 38 – 18 = 20 km/h

- There are 2 shirts. 3 jeans, 3 socks and 2 skirts. In how many ways a shopkeeper can arrange these things so that all the socks come together and all the skirts come together?

(A) 4690

(C) 2520

(B) 3260

(D) 5040

Ans: (D) 5040

We will count 3 socks as 1 socks and 2 skirts as 1 skirt.

Total ways = 7!

= 7 × 6 × 5 × 4 × 3 × 2 × 1 = 5040

- There is 90% increase in an amount in 9 years at simple interest. What will be the compound interest of Tk. 15000 after 4 years at the same rate?

(A) 4533

(B) 5497

(C) 6962

(D) 4965

Ans: (C) 6962

Interest Rate is 90/9=10%

So,

CI = 15000[(1+10/100)⁴-1]

=15000[(1.1)⁴-1]

=15000[1.4641-1]

=0.4641×15000

=6961.50

= 6962

- Two numbers are in ratio of 21:26. If 8 is added in each, the new members are in ratio of 5:6. Find the ratio of numbers, if 6 is subtracted from each number?

(A) 18:23

(B) 19:25

(C) 6:7

(D) 9:16

Ans: (A) 18:23

(21x +8)/(26x+8) = 5/6

Or, x = 2

Numbers are 42, 52

New ratio = (42-6)/(52-6) = 36/46 =18/23

- The ratio of milk to water in three containers of equal capacity is 3:2, 7: 3 and 11:4 respectively. The three containers are mixed together. What is the ratio of milk to water after mixing?

(A) 21:9

(B) 61 : 29

(C) 41:18

(D) 38.8

Ans: (B) 61 : 29

Let the capacity of each container be x.

Now, in first container there are 3 parts of milk and 2 parts of water. Mathematically it can be written as:

3/5x milk and 2/5x water.

Similarly, second container has 7/10x milk and 3/10x water.

And, third container has 11/15x milk and 4/15x water.

Now, after mixing:

Total milk = (3/5+7/10+11/15)x = 61/30x

Total water = (2/5+3/10+4/15)x = 29/30x

So, milk to water ratio is (61/30x)/(29/30x)

So, milk to water ratio is 61/29.

- If AB and CD are two diameters of a circle of radius r and they are mutually perpendicular, then what is the ratio of the area of the circle to the area of the ▴ACD?

(A) π/2

(B) π/4

(C) 2π

(D) π

Ans: (D) π

Required ratio = πr^{2}/{1/2(2r×r)} = π
