Question No 1

9 excavators working 10 hours a day remove 2500 cubic feet of earth in 3 days. How many excavators working 6 hours a day are required to remove 5000 cubic feet of earth in 2 days?

Select the correct answer

55 50 45 40

Solution!
Let x excavators are required.
As excavators are inversely proportional to hours and days and directly proportional to work progress so
x/9 = (10/6)*(5000/2500)*(3/2)
x = 45

Hence 45 excavators are required to remove 5000 cubic feet of earth..

Question No 5

A train travelling at he speed of 72km/h can cross a platform in 17 seconds. If length of the train is 180 meters, what is the length of the platform?

Select the correct answer

160m 170m 180m 190m

Solution!
Speed of train = v = 72Km/h = 72*(5/18) = 20m/s

Time = t = 17s
Length of the train = L1 = 180m
Length of the platform = L2 = ?

t = (L1+L2)/v
By putting values
17 = (180+L2)/20
340-180 = L2
L2 = 160m

Hence length of the platform is 160m..

Question No 8

What is the angle between the hands of a clock at 2:30?

Select the correct answer

120 degree 115 degree 105 degree 125 degree

Solution!
Hour hand is nearly at 2
Minute hand is at 6

Angle between 2 and 6 is 120 degree.

Hour hand move 1/2 degree in one minute.

In 30 Minutes hour hand will move 1/2 * 30 = 15 degree

Hence, Angle between hands is 120 - 15 = 105 degree.

Question No 9

Tina is twice as old as David. 15 years ago, Tina's age was 5 times the age of David. What is the present age of Tina?

Select the correct answer

20 35 40 30

Solution!
Let David's age is x and Tina's age is y.

Given that
y = 2x
y-2x = 0 ...(1)

and also given that
y-15 = 5(x-15)
y-15 = 5x-75
y-5x = -60 ...(2)

By simultaneously solving equation(1) and equation(2)
y = 40

Hence Tina's present age is 40 years..

Question No 10

An article was sold at a loss of 15% for $476. What is the cost price of the article?

Select the correct answer

$520 $540 $560 $580

Solution!
Let cost price of the article is x.
15% of x = (15x)/100 = 3x/20

Now
(3x/20) + 476 = x
3x+9520 = 20x
9520 = 17x
x = 560

Hence cost price of the article is $560..

Question No 11

A man can row 1 km upstream in 20 minutes, and downstream in 15 minutes. What is the speed of the current?

Select the correct answer

1 km/h 2 km/h 0.5 km/h 0.25 km/h

Solution!
20 minutes = 20/60 = 1/3 hours
Upstream distance covered in 1/3 hours = 1 Km
Upstream distance covered in 1 hour = 1/(1/3) = 3 Km
Upstream speed = y = 3 Km/h

Now
15 minutes = 15/60 = 1/4 hours
Downstream distance covered in 1/4 hours = 1 Km
Downstream distance covered in 1 hour = 1/(1/4) = 4 Km
Downstream speed = 4 Km/h

speed of water = (1/2)*(4-3) = 1/2 = 0.5 Km/h.

Question No 12

230 meters long train crosses a man sitting on the platform in 46 seconds. What is the speed of the train?

Select the correct answer

5m/s 10m/s 15m/s 20m/s

Solution!
Length of the train = L = 230m
Time = t = 46s
Speed = v = ?

V = L/t
By putting values
v = 230/46 = 5m/s

Hence speed of the train is 5m/s..

Question No 17

Ten years ago, P was half of Q in age. If the ratio of their present ages is 3/4, what will be the total of their present ages?

Select the correct answer

45 40 35 30

Solution!
Let the present age of P and Q be 3x and 4x respectively.

Ten years ago, P was half of Q in age.

(3x - 10) = 1/2 * (4x - 10)
6x - 20 = 4x - 10
2x = 10
x = 5

total of their present ages
= 3x + 4x = 7x = 7 * 5
= 35.

11x = 1/7
x = 1/77

Hence, A's 1 day's work = (1/77 * 7) = 1/11.

Select the correct answer

0 degree 10 degree 5 degree 20 degree

Solution!
Angle traced by hour hand in 13/3 hrs = (360/12 * 13/3) = 130 degree

Angle traced by minute hand in 20 min = (360/60 * 20) = 120 degree

So, required angle = 130 - 120 = 10 degree.
