so, let the present age of A and B be X and, (17-X).

then,

five years letter their age will be (X+5) and (22-X) years respectively.

after that, according to the question.,

$\frac{(x + 5)}{(22 - x)} = \frac{4}{5}$

$or \: \: 5x + 25 = 88 - 4x$

$or \: \: 9x = 88 - 25$

$or \: \: x = 7$

so, the present age of A is 7 years and B is 10 years.

(22−x)

(x+5)

=

5

4

or \: \: 5x + 25 = 88 - 4xor5x+25=88−4x

or \: \: 9x = 88 - 25or9x=88−25

or \: \: x = 7orx=7

so, the present age of A is 7 years and B is 10 years.

thanks a lot..
