Question No 2

By selling an article for $200 shopkeeper looses 20%. What is cost price of the article?

Select the correct answer


Solution!
Let cost price of the article is x.

20% of x = (x*20)/100 = x/5

Now
(x/5) + 200 = x
x+1000 = 5x
4x = 1000
x = 250

Hence cost price of the article is 250..

Question No 3

A boat running downstream covers a distance of 16 km in 2 hours while for covering the same distance upstream, it takes 4 hours. What is the speed of the boat in still water?

Select the correct answer


Solution!
Rate downstream = (16/2)km/h = 8 km/h

Rate upstream = (16/4)km/h
= 4 km/h

Hence, Speed in still water = 1/2(8+4)km/h = 6 km/h.

Question No 6

A man can row at 5 kmph in still water. If the velocity of current is 1 kmph and it takes him 1 hour to row to a place and come back, how far is the place?

Select the correct answer


Solution!
Speed downstream = (5 + 1) kmph = 6 kmph

Speed upstream = (5 - 1) kmph = 4 kmph

Let the required distance be x km.

Then,
x/6 + x/4 = 1
2x + 3x = 12
5x = 12

Hence, x = 2.4 km.

Question No 11

A train speeds past a pole in 15 seconds and a platform 100 m long in 25 seconds. Its length is

Select the correct answer


Solution!
Let the length of the train be x metres and its speed by y m/sec.

Then, x/y = 15
y = x/15

So, (x+100)/25 = x/15
15(x + 100) = 25x
15x + 1500 = 25x
1500 = 10x
x = 150 m.

Question No 12

A man rows 1 km upstream in 20 minutes and 1 km downstream in 15 minutes. What is his speed of rowing in still water?

Select the correct answer


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 rowing = (1/2)*(4+3) = 7/2 = 3.5 Km/h.

Question No 13

Question No 14

A train moves past a telegraph post and a bridge 264 m long in 8 seconds and 20 seconds respectively. What is the speed of the train?

Select the correct answer


Solution!
Let the length of the train be x metres and its speed by y m/sec.

Then,
x/y = 8
x = 8y

Now, (x+264)/20 = y
8y + 264 = 20y
y = 22

Hence, Speed = 22 m/sec
= 22 * (18/5)
= 79.2 km/hr.

Question No 15

Select the correct answer


Solution!
No answer description available for this question..

Question No 16

A train running at the speed of 60 km/hr crosses a pole in 9 seconds.What is the length of the train?

A man's age is three times his son's. In 15 years it will be double that of his son's. How old is the son now?

Select the correct answer


Solution!
Let Son's age is x
Mans Age = 3x

Given that
3x+15 = 2(x+15)
3x+15 = 2x+30
3x-2x = 30-15

x = 15

Hence son is 15 years old..

Question No 19

What will be the selling price of an article that was bought for $1150 and sold at profit of 6%?

Select the correct answer

Question No 20

The sum of ages of 5 children born at the intervals of 3 years each is 50 years. Find out the age of the youngest child?

Select the correct answer


Solution!
Let the ages of children be x, (x + 3), (x + 6), (x + 9) and (x + 12) years.

Then,
x + (x + 3) + (x + 6) + (x + 9) + (x + 12) = 50
5x = 20
x = 4

Hence, Age of the youngest child = x = 4 years.

Question No 23

The time in a clock is 20 minute past 2. Find the angle between the hands of the clock.

Select the correct answer


Solution!
Time is 2.20.
Hour hand at 2 (nearly) and minute hand at 4.

Angle between 2 and 4 is 60 degrees [(360/12) * (4-2)]

Angle made by the hour hand in 20 minutes is 10 degrees, since it turns through 1/2 degrees in a minute.

Therefore, angle between the hands is 60 degrees - 10 degrees = 50 degrees.

Question No 24

The difference of the ages of two brothers is 2 and the difference of the square of their ages is 16. The age of smaller one is?

Select the correct answer


Solution!
Let present age of elder brother is y and present age of younger brother is x.

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

and
(y^2)-(x^2) = 16
(y+x)(y-x) = 16

Put value of (y-x) from equation(1)
2(y+x) = 16
y+x = 8 ...(2)

By simultaneously solving equation(1) and equation(2) we have
y = 5
and
x = 3

Hence present age of younger brother is 3 years..

Question No 25

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

Select the correct answer


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 26

Ten years ago a father was seven times as old as his son, two years hence, twice his age will be equal to five times his son's. What is the present age of son?

Select the correct answer


Solution!
Let present age of son is x and present age of father is y.

Given that
y-10 = 7(x-10)
y-10 = 7x-70
y-7x = -70+10
7x-y = 60 ...(1)

and also given that
2(y+2) = 5(x+2)
2y+4 = 5x+10
2y-5x = 6 ...(2)By simultaneously soving equation(1) and equation(2)
x = 14

Hence present age of son is 14 years..

Question No 52

Ages of A and B are in ratio 8/7. 27 years ago their ages were in the ratio 5/4. The age of B is

Select the correct answer


Solution!
Given that
A/B = 8/7 ...(1)

and
(A-27)/(B-27) = 5/4
5B-135 = 4A-108 ...(2)

From equation(1) we have
A = (8/7)B

Put value of A in equation(2)
5B-135 = 4*[(8/7)B]-108
5B-27 = (32/7)B
5B-(32/7)B = 27
(35B-32B)/7 = 27
3B = 189
B = 63

Hence the age of B is 63 years..
