A. 24 years

B. 30 years

C. 18 years

D. 33 years

Answer: Option B

Solution(By Examveda Team)

Let Maya's and Chhaya's present age is 6x and 5x respectively
And,
$$\frac{{6{\text{x}} + 15}}{{5{\text{x}} + 15}} = \frac{9}{8}$$
Or, 48x + 120 = 45x = 135
Or, 3x = 15
Or, x = 5
Present age of Maya = 6x = 30
