If the ratio of the ages of Maya and Chhaya is 6:5 at present, and fifteen years from now, the ratio will get changed to 9:8, then find Maya's present age.
Correct answer: B
Explanation
Let Maya's and Chhaya's present age is 6x and 5x respectively.
And,
(6x+15)/(5x+15) = 9/8;
Or, 48x+120 = 45x = 135;
Or, 3x = 15;
Or, x = 5;
Present age of Maya = 6x = 30.
