If Diana was 25 years old 5 years ago, how old will be she x years after?

  1. 30-x
  2. 20+x
  3. 30+x
  4. x-30
  5. x-20
Explanation

Answer: C

Work out this problem in two stage: first find the present age and then add x to find her age after x years.

Present age = 25 +5 = 30, so she will be 30+x after x years.

Key takeaway: Age related word problems are more based on logic than calculation. Some practice needs to be done to solve in a simple way.
