Question

Rajesh is 22 years older than his son who is 8 year old. after how many year old the age of Rajesh Be 2 time that of his son.

Answer 1

son's age = 8
Rajesh's age = 8+22 = 30
after x years,
son's age = 8+x
Rajesh's age= 30 + x
2(8+x) = 30+x
16 + 2x = 30 + x
x = 14
ie. after 14 years.

Hope it's helpful. Please mark me as the brainliest.

Answer 2

sons present age is 8 years
his father age is 8+22=30 years
according to question
2(age of son) = age of father
let this happen after x years
2(8+x)=30+x
16+2x=30+x
x= 14 years
.so after 14 years age of rajesh will he 2 times his son age
