Question

Difference between 3/5 of Raman's present age and his age 4 years ago is zero. What will be his age after 5 years?

Answer 1

Answer: 15 years

Explanation:

Given

Difference between
`(3)/(5)` Raman's present age and his age 4 years ago is 0

Suppose Raman's present age is
`x`

So, we can write

`\Rightarrow (3x)/(5)-(x-4)=0\\\Rightarrow (3x-5x)/(5)+4=0\\\Rightarrow (-2x)/(5)+4=0\\\Rightarrow x=(20)/(2)=10`

His age after 5 years is
`x+5=15\ yr`
