Question

Five years ago, the ratio of A's age and B's age
was 5:6. The ratio of their ages will be 7: 8 after
five years. What is the ratio of the A's present
age and the B's present age?​

Answer 1

Answer:

Let A present age is a.

Let B present age is b.

For,

a:b = 5:6 

Let the common multiple be c. there fore,

a=5c and b=6c and

A age fine years from now is a+5 

B age fine years from now is b+5 

hence, 

  (a+5):(b+5)=6:7

 ⇒ 6c+55c+5=76

⇒ 35c+35=36c+30

hence the c=5

hence the present age of A is 25

and B is 30

Answer 2

Answer:

6:7 is your answer .

6v7 is their ratio
