Answer:
10 years old
Step-by-step explanation:
The difference in ages is 60 -30 = 30 years. When mom was 4 times daughter's age, the difference in their ages was 3 times the daughter's age.
The age difference was 30 years at that time, so the daughter was 10 years old.
It’s 6x6=36, because if 4 over 2 was 4 twice then 6 over 2 is 6 twice.
