Answer 1

Answer:

25 Years ago their age was in the ratio 1:3 !!

Step-by-step explanation:

Let the year be x

Given :- The present age of Reennt is 30 years and the present age of Geetu is 40 years !!

x years ago , there age was as :-

Reennt's age = ( 30 - x ) years !!

and Geetu's age = ( 40 - x ) years !!

Given ; ratio :-

$\frac{30 - x}{40 - x} = \frac{1}{3}$

90 - 3x = 40 - x

50 = 2x

25 = x

So, 25 years ago the ratio of their age was 1:3

Answer 2

Reennt's age = ( 30 - x ) years

and Geetu's age = ( 40 - x ) years
