Murali’s present age is half of his father’s age. Before 10 years, his father’s
age was thrice his age. Find the present age of Murali and his father.
A. 16, 32 years B. 15, 30 years
C. 20, 40 years D. 17, 34 years

• C. 20, 40 years
  
  If present ages of Murali=M and Father=F, then
  M=F/2 or F=2M ---(i)
  Also 3(M-10)=F-10 or 3M-F=20 ---(ii)
  Comparing (i) & (ii), M=20, F=40
