Ans:A

Exp: Let present age of P and Q be ‘x’ and ‘y’ years respectively.

x + y = 52 …(i)

and,

= ⇒ 5x + 20 = 4y – 8

⇒ 5x – 4y = – 28…(ii)

From (i) and (ii)

x = 20 years.

P’s age 5 years later = 25 years.

33. An article is sold at a profit of th of its CP to a person. That person further sold it at 20%
