Answer 1

QUESTION:-

The present age of Aradhana and Aadrika is in the ratio 3:4. 5 years back, the ratio of their ages was 2:3. What is the present age of Aradhana?

12 years

15 years

20 years

22 years

10 years

EXPLANATION:-

Let the present age of Aradhana=3x

and that of Aadrika=4x

5 years back their ages:-

Aradhana=3x-5

Aadrika=4x-5

ATQ,

$\bf\;\frac{3x-5}{4x-5}=\frac{2}{3}\\\\(3x-5) = 2(4x-5)\\\\9x-15 = 8x-10\\\\x = 5$

Therefore, Aradhana’s current age = 3×5 = 15 years
