Question

12 year ago the ratio between the ages of A and B was 3 : 4 respectively. The present age of A is 3

of C's present age. If C's present age is 10 yr, then what is B's present age? (in years)​

Answer 1

I would say 40

Step-by-step explanation:

I say this because a is 3 of c's wait and thats 3×10 so you would also have to do 4×10 which is 40 making the ratio 30:40 making b's age 40
