Question

Current age is 5:7 sum of age after 4 year is 56 find current age

Answer 1

{ Please, write the complete question to get a better answer. I am adding the answer though. }

Answer :

Given that, the ratio of current ages is 5 : 7

Let, x be the common ration

Then, the ages of them be 5x years and 7x years respectively

After 4 years, they will be (5x + 4) years and (7x + 4) years respectively

By the given condition,

(5x + 4) + (7x + 4) = 56

==> 5x + 4 + 7x + 4 = 56

==> 12x + 8 = 56

==> 12x = 56 - 8

==> 12x = 48

==> x = 48/12

==> x = 4

Therefore, their current age be

(5 × 4) years and (7 × 4) years respectively

i.e., 20 years and 28 years respectively

Answer 2

hey dear...

let 5:7 be 5x and 7x respectively...

after 4 yrs it will be (5x+4) and (7x+4) resp.

(5x+4)(7x+4)=56

12x+8=56

12x=48

x=4....

now,put value of x in ratio,

5X4=20 and 7X4=28 ages....

thnx for asking dear......
