Best answer
Correct Answer - Option 4 : 14 years

Given

Present age of Sudhir = 1.4 times of Suman’s age

After seven years ratio of their ages = 19 ∶ 15

Formula used

Ratio formula, a ∶ b = a/b

Calculation

Let present age of Suman = x years

So present age of Sudhir = 1.4x

According to question

⇒ (1.4x + 7)/(x + 7) = 19/15

⇒ 15(1.4x + 7) = 19(x + 7)

⇒ 2x = 133-105

⇒ x = 28/2

⇒ x = 14 years

the present age of Suman is 14 years.
