Answer 1

Anu if 4 year older than sunil.
if sunil age=x
anu age=x+4
Anu was 3 times sunil's age 8 years ago
(x+4)-8=3(x-8)
x-4=3x-24
x-3x= -24+4
-2x= -20
x=10
sunil's age=10
anu's age=10+4=14

Answer 2

let

present age of sunil to be x

then present age of anu would be x + 4

eight years ago age of sunil is x - 8

eight years ago age of anu is x + 4 - 8 = x - 4

ATQ

x - 4 = 3 ( x - 8 )
x - 4 = 3x - 24
2x = 20
x = 10

there fore present age of sunil is x = 10

anu is x+4 = 10+4 = 14
