In 2002, Meenu's age was one-third of the age of Meera

Linear Equations

In 2002, Meenu's age was one-third of the age of Meera, whereas in 2010, Meenu's age was half the age of Meera. What is Meenu's year of birth?

  1. 1992
  2. 1994
  3. 1996
  4. 1998

Answer

In 2002, let Meera's age be r and Meenu's age be n.

So, n = 1/3 × r

r = 3n

In 2010, after eight years from 2002

(n + 8) = 1/2 × (r + 8)

2n + 16 = r + 8

2n + 8 = 3n

n = 8

So, Meenu's age in 2002 was 8 years.

Year of birth was 2002 - 8 = 1994.

The correct option is B.
