Question

Lisa is 42 years old now. She is 30 years older than her son, joshua. How old will Lisa be when she is 3 times as old as joshua?

Answer 1

Answer:66 years

Step-by-step explanation:

Lisa = 42 years

Joshua = 42-30 = 12 years

Joshua's age 3 times == 12*3 = 36 years

After 24 years, Joshua will be thrice his age.

Lisa = 66 years                                          [42+24  or 36+30]
