Ages (Sonu and Bulla) = 4 : 3
Sum = 49 years
Calculation:
Let the age of Sonu and Bulla be 4m and 3m.
According to the question,
⇒ 4m + 3m = 49
⇒ 7m = 49
⇒ m = \(\dfrac{49}{7}\) = 7
Ratio of ages after 4 years = (4m + 4) : (3m + 4)
⇒ (4 × 7 + 4) : (3 × 7 + 4)
⇒ 32 : 25
∴ The ratio of their ages after 4 years is 32 : 25.
