Question

Vikas age is three year older than deepika.Six years ago vikas age was 4 times of deepika,s age .Find vikas and deepika age?

Answer 1

Let age of Vikas is x and age of Deepika be y
Given = x=3+y
6year ago = x =4y
2 equations
= x= 3+y. _a
= x =4y. _b
=X/4=y. _c
Substitute c in a
= x = 3+x/4
=x =(12+x)/4
= 4x=12+x
= 3x = 12
= x. =4. _1
Substitute x=4 in a
=x=3+y
=4=3+y
=y=1
Therefore in this equation x=4 and y=1
