Anita is 4 times as old as her son today. After 6 years she will be 3 times as old as him. What is Anita's present age?
Anita is 48 years old, since 4s + 6 = 3(s + 6) gives s = 12.
- A24 yearsCorrect
- B36 years
- C30 years
- D32 years
Explanation
Let the son's age be s, so Anita's is 4s. Then 4s + 6 = 3(s + 6), so s = 12 and Anita = 48. Check: after 6 years 54 and 18, a ratio of 3. So 48 is correct, which is not listed.
