Question

The present age difference between father and son is 14 years. The ratio of their age will be 4 : 3 after 11 years. How old is son now?

• A. 25 years
  
• B. 31 years
  
• C. 30 years
  
• D. 28 years
  
• E. None of these

Answer 1

The correct option is D 28 years


Let present age of father be x years.
Present age of son =(x-13) years
According to the question,
$\frac{x+11}{(x-13)+11}=\frac{4}{3}\Rightarrow 3x+33=4x-8\Rightarrow x=41$
Thus, present age of son =41-13
=28 years.
