Question

five years ago, ananya's mother was 5 times as old as ananya. if her mother is now three times as old as anany, find their present age

Answer 1

Let the present age of ananya be x years
and present age of her mother be y years :

y=3x --------(1)

(y-5) = 5(x-5)
y-5 = 5x-25

y = 5x-20 -------(2)

3x = 5x-20
2x = 20
x = 10

y=3x
= 3×10
y = 30

Hence the present age of ananya is 10 years and that of her mother is 30 years.

Answer 2

Answer:

Let the present age of ananya be x years

and present age of her mother be y years :

y=3x --------(1)

(y-5) = 5(x-5)

y-5 = 5x-25

y = 5x-20 -------(2)

3x = 5x-20

2x = 20

x = 10

y=3x

= 3×10

y = 30

Hence the present age of ananya is 10 years and that of her mother is 30 years.
