Answer 2

Given :-

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

To Find :-

• What is the present age of Aradhana.

Solution :-

⟼ Let the present age of Aradhana be 3x

⟼ Let the present age of Aadrika be 4x

Before 5 years :

⟼ Aradhana’s age = (3x - 5)

⟼ Aadrika’s age = (4x - 5)

According to the Question :

⟾⠀⠀ (3x - 5) ÷ (4x - 5) = 2/3

⟾ ⠀⠀3(3x - 5) = 2(4x - 5)

⟾ ⠀⠀9x - 15 = 8x - 10

⟾⠀⠀ 9x - 8x = - 10 + 15

⟾⠀⠀⠀⠀⠀⠀x = 5

________________

Thus, Present age of Aradhana = 3x = 3 × 5 = 15years
