ATQ, Let the ages of Rohan and Sohan 8 years ago be 5x years and 6x years, respectively. Age of Mohan 8 years ago 5x3 years Age of Rohan now 5x8 Age of Sohan now 6x8 Five years hence Age of Rohan 5x855x13 Age of Sohan 6x856x13 Age of Mohan 5x1335x10 Given Solving the equation 75x1066x13 35x7036x78 36x35x7078 x8 Since 10 is the smallest two-digit composite number Age of Rohan, 10 years hence 5x8105881058 years.

Sohan was 5:6, respectively. Five years hence, the ratio of the ages of Mohan and Sohan will be 6:7, respectively. If Mohan is 3 years younger than Rohan, find the age of Rohan, 'a' years hence, where 'a' is the smallest two-digit composite number.

A 30 yrs

B 36 yrs

C 58 yrs

D 40 yrs
