Question

priyas mother is 4 times as old as priya after 5years, her mother will be 3 times as old as she wil be then. what are their present ages

Answer 1

according to the question
let age of mother x and age of priya y
4(x)=(y+5)
4x-y=5
x-y=5/4
x=5/4-y.....1
3(x)=(y)
3x-y=0
putting the value of x
3(5/4-y) -y=0
(15/4-4y) -y=0
15-16y-4y/4=0
15-20y=0
-20y=-15
y=3/4
putting value of y in equation 1
x=5/4-3/4
=2/4=1/2
