Question No 3

A mother's age after 5 years, will be twice the age of her daughter. The difference of their ages is 19. What is the age of mother?

Select the correct answer


Solution!
Let present age of daughter is x and present age of mother is y.

Given that
y+5 = 2(x+5)
y+5 = 2x+10
5-10 = 2x-y
y-2x = 5 ...(1)

and also given that
y-x = 19 ...(2)

By simultaneously solving equation(1) and equation(2) we can find
y = 33

Hence mothers present age is 33 years..

Question No 4

A goods train runs at the speed of 72 kmph and crosses a 250 m long platform in 26 seconds. What is the length of the goods train?

Select the correct answer


Solution!
Speed = 72 * (5/18)m/s
= 20 m/s

Time = 26 sec

Let,
the length of the train be x metres

Then,
(x+250)/26 = 20

x + 250 = 520
x = 270.

Question No 5

Question No 6

What is 45% of 300?

Select the correct answer


Solution!
45 * (300/100) = 135

Quick way to find answer from options is

50% of 300 is 150 so 45% of 300 should be less than 150

So, it may be 149 or 135
149 is very close to 150 which is not possible

Hence, 135 is correct answer..

Question No 7

If a man takes two hours to row 3 km upstream or 15 km downstream then the speed of current is?

Select the correct answer


Solution!
Upstream distance covered in 2 hours = 3Km
Distance covered in 1 hour = 3/2 = `1.5 Km
So,
Upstream speed = 1.5 Km/h
Downstream distance covered in 2 hours = 15Km
Distance covered in 1 hour = 15/2 = 7.5Km

Downstream speed = 7.5 Km/h

Now
Speed of water = (1/2)*(7.5-1.5) = 3 Km/h.

Question No 8

The ages of C and D are in 6/11 and E is 6 years younger than D. If the sum of ages is 134, then what is the age of D?

Select the correct answer


Solution!
Given that
C/D = 6/11
C = (6/11)D ...(1)

and
C+D+E = 134

As E is 6 years younger from D so we can put D-6 instead of D
C+D+D-6 = 134
C+2D = 140
Put value of C from equation(1)
(6/11)D+2D = 140
6D+22D = 140
28D = 1540
D = 55

Hence D is 55 years old..

Question No 9

Question No 12

A trader mixes 26 kg of rice at Rs. 20 per kg with 30 kg of rice of other variety at Rs. 36 per kg and sells the mixture at Rs. 30 per kg.His profit percent is

Select the correct answer


Solution!
C.P. of 56 kg rice = (26 x 20 + 30 x 36) = (520 + 1080) = Rs. 1600

S.P. of 56 kg rice = Rs. (56 x 30) = Rs. 1680

Hence, Gain = (80/1600)*100 = 5%.

Question No 13

The reflex angle between the hands of a clock at 10:25 is

Select the correct answer


Solution!
Angle traced by hour hand in 125/12 hrs = (360/12 * 125/12) = 625/2 degree

Angle traced by minute hand in 25 min = (360/60 * 25) = 150 degree

So, Reflex angle = 360 - (625/2 - 150) = 197.5 degree.
