Question

Anu is 4 years older than Sunil 8 years ago and anu was three times Sunil's age find the ages of Anu and Sunil

Answer 1

let age of anu = x age of sunil= y
x= 4 + y
8 years ago
(x-8)=3(y-8)
(4+y-8)=3y-24
(-4+y)=3y-24
-4+24=3y-y
20=2y
y=10
x=4+10=14

Answer 2

Anu is 4 year older than Sunil
If Sunil's age = x
Anu's age = x+4

Anu was 3 times Sunil's age 8 years ago
(x+4) - 8 = 3(x-8)
x-4 = 3x - 24
-4 +24= 3x-x
20 = 2x
10=x
Sunil's age = x = 10years
Anu's age = x+4 = 10+4= 14years
