Question No 2

By selling a car for Rs. 495000 an agent gains 10%. What was his cost?

Select the correct answer


Solution!
Let cost price of the car is x.
10% of x = 10x/100 = x/10

Now
495000 - (x/10) = x
4950000 - x = 10x
4950000 = 11x
x = 450000.

Question No 3

A motorboat, whose speed in 15 km/hr in still water goes 30 km downstream and comes back in a total of 4 hours 30 minutes. The speed of the stream (in km/hr) is

Select the correct answer


Solution!
Let the speed of the stream be x km/hr.

Then,
Speed downstream = (15 + x) km/hr

Speed upstream = (15 - x) km/hr

So, [30/(15 + x)] + [30/(15 - x)] = 9/2
900/(225 - x*x) = 9/2

x = 5 km/hr.

A man is 24 years older than his son. In two years, his age will be twice the age of his son. What is the present age of his son?

Select the correct answer


Solution!
Let the present age of the son = x years

Then present age the man = (x+24) years

Given that in 2 years, man's age will be twice the age of his son

(x+24) +2 = 2(x+2)
x = 22.

Question No 12

A works twice as fast as B.If B can complete a work in 12 days independently,The number of days in which A and B can together finish the work in

Select the correct answer


Solution!
Ratio of rates of working of A and B = 2/1

So, ratio of times taken = 1/2

B's 1 day's work = 1/12

A's 1 day's work = 1/6
(2 times of B's work)

(A + B)'s 1 day's work = (1/6 + 1/12) = 1/4

So, A and B together can finish the work in 4 days..

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 23

A train is travelling at the speed of 25m/s. In what time will it pass a man sitting on a platform if length of the train is 225 meters?

Select the correct answer


Solution!
Speed = v = 25m/s
Length of train = L = 225m

Time = t = L/v
t = 225/25 = 9

Hence train will pass the man in 9 seconds..

Question No 24

A train 108 m long moving at a speed of 50 km/hr crosses a train 112 m long coming from opposite direction in 6 seconds. The speed of the second train is

Select the correct answer


Solution!
Let the speed of the second train be x km/hr.

Relative speed = (x + 50) km/hr
= (x+50)*(5/18) m/s
= (250+5x)18 m/s

Distance covered = (108 + 112) = 220 m

So, 220/[(250 + 5x) /18] = 6
250 + 5x = 660

Hence, x = 82 km/hr.

Question No 25

Question No 27

The sum of the ages of a son and a father is 64. After 4 years the age of father will be three times that of his son's. The age of father is

Select the correct answer


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

Given that
x+y = 64 ...(1)

and
y+4 = 3(x+4)
y+4 = 3x + 12
y-3x = 8 ...(2)

Put value of x from equation(1) in equation(2)

y-3(64-y) = 8
y-192+3y = 8
4y = 200
y = 50

Hence present age of the father is 50 years..

Question No 28

Q is as much younger than R as he is older than T. If the sum of the ages of R and T is 50 years, what is definitely the difference between R and Q's age?

Select the correct answer


Solution!
Given that

(i)The difference of age b/w R and Q = The difference of age b/w Q and T
(ii) (R + T) = 50

So,R - Q = Q - T

(R + T) = 2Q

Now given that, (R + T) = 50

So, 50 = 2Q and therefore Q = 25

Question is (R - Q) = ?

Here we know the value(age) of Q (25), but we don't know the age of R.

Therefore, (R-Q) cannot be determined..
