Ana is 10 years old and her mother is 4 times as old as she is. How old will her mother be in 5 years?
Answer and explanation
Correct answer: D. 45 years
- Step 1: The mother is 4 x 10 = 40 now, so in 5 years she will be 40 + 5 = 45. Answer: 45 years. Why not the others: 40 years, 15 years and 90 years don't fit.
