Correct Answer: 45


Solution : Given: Ravi is 12 years younger than Surya. Ravi's age is 40% of the sum of his and Surya's ages.
Let Ravi's age be $x$ years.
Then, Surya's age $= (x+12)$ years
According to the question,
$x = [x+(x+12)]×\frac{40}{100}$
⇒ $5x= 4x+24$
⇒ $x = 24$
Surya's age after 9 years $=x+12+9 = x+21 = 24+21 = 45$ years.
Hence, the correct answer is 45.
