Question

The present age of Hari Kishan is 60 years. The present age of
Manish is 30 years. The ratio of the age of Manish to the age of
Hari Kishan 10 years ago was
a) 2:5
b) 5:2
c) 2:3
d) 3.2.​

Answer 1

Answer:

The ratio of Hari's and Harry's present ages is 5:7

So, let their ages be 5x and 7x

After 4 years their ages will be in ratio 3:4

Therefore,(5x+4)/(7x+4)=3/4

or, 4(5x+4)=3(7x+4)

or, 20x+16=21x+12

or, 16−12=21x−20x

or, 4=1x

or, x=4

Therefore, present age of Hari = 5x=(5×4)=20 years.

Present age of Harry =7x=(7×4)=28 years

The sum of their age is 28+20=48years
