PKB Executive Officer Preli Exam Solution 2019 : SECTION-C : GENERAL MATHEMATICS

PKB Executive Officer Preli Exam Solution 2019 : Questions (33-56): Read the following questions carefully and choose the right answer.

33. Two trains of equal length are running on parallel lines in the same direction at 46 km/hr and 36 km/hr. The faster train passes the slower train in 36 seconds. The length of each train is:

(A) 50 m

(B) 72 m

(C) 80 m

(D) 82 m

Answer: (A) 50 m

Let the length of each train be x metres.

Then, distance covered = 2x metres.

Relative speed = (46 – 36) km/hr

=(10 ×5/18)         m/sec

=(25/9)m/sec

2x/36=25/9

Or, 2x = 100

Or, x= 50

34. A takes twice as much time as B or thrice as much time as C to finish a piece of work. Working together, they can finish the work in 2 days. B can do the work alone in

(A) 4 days

(B) 8 days

(C) 6 days

(D) 12 days

Answer: (C) 6 days

A, B and C take x, x/2 and x/3 days respectively to finish the work.

Then,

1/x+2 /x +3/x=1/2

Or, 6/x=1/2

Or, x = 12.

B takes (12/2) = 6 days

35. The percentage profit earned by selling an article for Tk. 1920 is equal to the percentage loss incurred by selling the same article for Tk. 1280. At what price should the article be sold to make 25% profit?

(A) Tk. 2000

(B) Tk. 2200

(C) Tk. 2400

(D) Data inadequate

Answer: (A) Tk. 2000

Let C.P= Tk X

Then, (1920 – x)/x  =(x-1280)/x

1920 – x = x – 1280

2x = 3200

x = 1600

S.P. = 125% of 1600 = (125/100 x 1600)= 2000 tk

36. A person travels a certain distance at 3 km/hr and reaches 15 min late. If he travels at 4 km/hr, he reaches 15 min earlier. The distance he has to travel is

(A) 4.5 km

(B) 6 km

(C) 7.2 km

(D) 12 km

Answer: (B) 6 km

Let,

the time taken to travel at speeds 3 km/h and 4 km/h be t1and t2 respectively.

So, t1 – t2 = 15 – (-15) = 30   minutes = 0.5 h

Now, let the distance travelled be = x km

So, (x / 3) – (x / 4) = 0.5

Or, x = 6 km

37. A boy travelled from the home to the college at the rate of 25 km/hr and walked back at the rate of 4 km/hr. If the whole journey took 5 hours 48 minutes. Find the distance of the college from the home.

(A) 5 km

(B) 10 km

(C) 15 km

(D) 20 km

Answer: (D) 20 km

Average speed = 2ab/(a+b) here a=25 b=4

= 2x25x4/(25+4)=200/29 km/hr.

Distance covered in 5 hours 48 minutes

= Speed x time = (200/29)x (29/5)

Distance covered in 5 hours 48 minutes = 40kms

Distance of the post office from the village = (40/2)=20 km.

38.(√1372 +√959) ÷ √292 × 19.003 = ?

(A) 77

(B) 97

(C) 39

(D) 19

Answer: (A) 77

(√1372+ √959) ÷ √292 × 19.003

= (37.04 + 30.96) ÷ 17×19.003

= (68/17) × 19.003

= 76.012  aprx to 77

39. Two men and three women can repair a bridge in 10 days while three men and two women can do the same work in 8 days. If two men and one woman are used to finish this work, in how many days they will complete it?

(A) 15.0 days

(B) 13.5 days

(C) 11.0 days

(D) 12.5 days

Answer: (D) 12.5 days

Let 1 man’s 1 day’s work = x and 1 woman’s day’s work = y.

Then, 2x + 3y =  1/10  and 3x + 2y =  1/8

(2 men and 1 woman)’s 1 day’s work =

2 ×7/200 + 1 ×1/100=2/25

So, 2 men and 1 woman together can finish the work in  25/2  = 12.5 days.

40. A boatman takes twice as long to go a distance upstream as to travel the same distance downstream. What is the ratio of the speed of the boatman(in still water) and the current?

(A) 2:3

(B) 3:1

(C) 1:3

(D) 4:3

Answer: (B) 3:1

Let man’s rate upstream =x kmph.

Then, his rate downstream = 2x kmph.

(Speed in still water) : (Speed of stream)

= (2x + x)/2: (2x – x)/2

=3x/2: x/2

= 3 : 1

41. Speed of a boat in standing water is 9 km/hr and the speed of the stream is 1.5 km/hr. A man rows to a place at a distance of 105 km and comes back to the starting point. The total time taken by him is:

(A) 14

(B) 16

(C) 24

(D) 20

Answer: (C) 24

speed upstream = 9-1.5=7.5 kmph.

Speed downstream = 9+1.5=10.5 kmph.

Total time taken =         (105 /7.5+ 105/10.5)hours = 24 hours

42. A, B and C investsed capital in the ratio of 4:6:9. At the end of the business term, they received the profit in the ratio 2:3:5. Find the ratio of their time for which they contributed their capitals.

(A) 1:1:9

(B) 2:2:9

(C) 10:10:9

(D) 9:9:10

Answer: (D) 9:9:10

Here, profit ratio= P1 : P2 : P3 = 2 : 3 : 5

and investment’s ratio= x1 : x2 : x3 = 4 : 6 : 9

Required ratio = P1/x1 : P2/x2 : P3/x3

= 2/4 : 3/6 : 5/9

= 1/2 : 1/2 : 5/9 = 9 : 9 : 10

43. A trader marks his goods at 20% above the cost price. If he allows a discount of 5% for cash down payment, his profit percent for such a transaction is

(A) 15%

(B) 12%

(C) 14%

(D) 17%

Answer: (C) 14%

CP= 100

MP= 120

at 5% discount SP = 120- 120*5/100= 114

profit = 114-100= 14%

44. If a = √3/2, then √(1+ a) + √(1-a) =?

(A) √3

(B) (2-√3)

(C) (2+√3)

(D) √3/2

Answer: (A) √3

Let, √(1+a) + √(1-a) = x

Or,[√(1+a) + √(1-a)]² = x²

Or, 1+a + 2√(1+a)(√1-a) + 1-a = x²

Or, 2 + 2√(1-a²) = x²

Or, 2 + 2√[1 – (√3/2)²]= x²

Or, 2 + 2√(1 – 3/4) = x²

Or, 2 + 2 × 1/2 = x²

Or, x² = 3

Or, x = √3

so, √(1+a) + √(1-a) = √3.

45. Some money is divided amongst three workers A, B and C such that 5 times A’s share is equal to 12 times B’s share which is equal to 6 times C’s share. The ratio between the shares of A, B and C is?

(A) 5:10:12

(B) 10:12:5

(C) 12: 5:10

(D) 5:12:10

Answer: (C) 12: 5:10

Let 5A = 12B = 6C = x

Then, A = x/5, B = x/12 and C = x/6

∴ A : B : C = x/5 : x/12 : x/6 = 12 : 5 : 10

46. At simple interest of 5%, 6% and 8% for three consecutive years, the interest earned is Tk. 760. Find the principle?

(A) Tk.4000

(B) Tk.4600

(C) Tk.3200

(D) Tk.3600

Answer: (A) Tk.4000

Let the principle be tk P

Then,

(P x 1 x 5)/100 + (P x 1 x 6)/100 + (P x 1 x 8)/100 = 760

Or, 5P/100 + 6P/100 + 8P/100 = 760

Or, 19P = 760 x 100

Or, P = (760 x 100)/19 = tk 4000

Hence, the principle is tk 4000.

47. If the compound interest of a certain sum of money for two successive years be Tk. 225 and Tk. 238.50. What is the rate of interest per annum?

(A) 5%

(B) 7%

(C) 10%

(D) 6%

Answer: (D) 6%

The simple interest of Tk 225 for one year is Tk(238.50 – 225).

So Rate = (simple interest x 100 )/( time x principle)

= {(238.50 – 225) x 100}/(225 x 1) = 1350/225 = 6%

48. A bag contains 4 white, 5 red and 6 blue balls. Three balls are drawn at random from the bag. The probability that all of them are red, is

(B) 5/42

(C) 17/42

(D) 3/14

Answer: (C) 17/42

Total outcome= ⁹C₃

More than one vowels can be chosen= (⁴C₂×⁵C₁)+⁴C₃

[ 2 vowels + 1 consonant  or  3 vowels ]

Probability = (⁴C₂×⁵C₁)+⁴C₃/ ⁹C₃ = 17/42

50. The ages of X and Y are in the proportion of 6:5 and total of their ages is 44 years. The proportion of their ages after 8 years will be

(A) 8:7

(B) 3:6

(C) 6:3

(D) 9:5

Answer: (A) 8:7

Let, X: Y= 6a:5a

Or, 6a+ 5a= 44

Or, a = 4

Proportion of ages after 8 years will be=

6a + 8 : 5a+ 8  =  32:28= 8:7

51. The volume of a wall, 5 times as high as it is broad and 8 times as long as it is high, is 12.8 m³. Find the breadth of the wall.

(A) 30 cm

(B) 40 cm

(C) 50 cm

(D) 60 cm

Answer: (B) 40 cm

Let, breadth = x m

so, Height = 5x m and Length = 40x m

Or, x³ = 12.8/200

Or, x=  0.4m = 40cm

52. A rectangular field is to be fenced on three sides leaving a side of 20 m uncovered. If the area of the field is 680 m², how many meters of fencing will be required?

(A) 88 m

(B) 34 m

(C) 40 m

(D) 68 m

Answer: (A) 88 m

Let, Length= L & Breadth =20 m (Which is uncovered)

so, L× 20 = 680

Or, L = 34 m

Area to be fenced = 2L + 1breadth = 2×34 + 20 = 88 m

53. A number is decreased by 10% and then increased by 10%. The number so obtained is 10 less than the original number. What was the original number?

(A) 4000

(B) 3000

(C) 2000

(D) 1000

Answer: (D) 1000

Let,

The number =x.

ATQ,

110% of (90% of x) =(110/100 × 90/100 × x) = (99/100)x.

Or, x-(99/100)x=10

Or, x =1000

(A) 140

(B) 196

(C) 84

(D) 240

Answer: (C) 84

3A = 4B = 7C = x

so,  A = x/3, B = x/4 and C= x/7

A : B : C = x/3 : x/4 : x/7 = 28:21 :12.

C’s share = Tk {427 x (12/61)} = Tk 84

56. A and B invest in a business in the ratio 3 : 2. If 5% of the total profit goes to charity and A’s share is 33 Tk. 855, the total profit is:

(A) 500

(B) 2000
