Question

Sum of the ages of two brothers Amit and Sumit is 42 years. Before 6 years, Sumit's age was double the age of Amit. Find the present age of Sumit.

Answer 1

before 6 years
let age of amit=x
let age of sumit=2x
ATQ
x + 2x = 42
3x = 42
x = 42÷3
x = 14
age of sumit = 2x
= 2×14
= 28 years

Answer 2

let the age of amit be x
let the age of sumit be 42-x

summit's age six yrs before =42-x-6
amit s age if yrs before =x-6

ATQ
42-x=2(x-6)
42-x=2x-12
-x-2x=-12-42
-3x=-54
x=18

age of amit=18
age of sumit =42-18=24
