Question

Ages of A and B are in the ratio 3 ratio 4 6 years from now their ages would be in the ratio 5 ratio 6 the ages of A and B are now

Answer 1

Answer:

Let A present age is a.

Let B present age is b.

For,

a:b = 3:4

Let the common multiple be c. there fore,

a=3c and b=4c and

A age fine years from now is a+5

B age fine years from now is b+5

hence,

(a+5):(b+5)=5:6

3c+5

4c+5

=

5

6

⇒ 18c+30=20c+25

hence the c=5/2

hence the present age of A is 15/2

and B is 10
