Question

Kiran is 24 years older than Rakesh .10 year back kirans's age was five times the age of Rakesh .find their ages​

Answer 1

Kiran is 24 years older than rakesh .

K = 24 + R.......(1)

Ten years back kirans age was 5 times

the age of rakesh.

K - 10 = 5(R - 10).....(2)

K - 10 = 5R - 50.......(2)

Substitute (24 + R) from Eq(1)

in place of K in Eq(2)

K - 10 = 5R - 50.......(2)

(24 + R) - 10 = 5R - 50

Remove brackets

24 + R - 10 = 5R - 50

Collect like terms:

R - 5R = - 50 + 10 - 24

-4R = -64

R = 16

Rakesh is 16 years old.

Kiran is 40 years old.

Hope this helps :-)
