Ana is 12 years old and her mother is 4 times as old as she is. How old will her mother be in 4 years?
Answer and explanation
Correct answer: B. 52 years
- Step 1: The mother is 4 x 12 = 48 now, so in 4 years she will be 48 + 4 = 52. Answer: 52 years. Why not the others: 48 years, 16 years and 96 years don't fit.
