Question

A father's age is equal to the total age of his three children . after 5 years,the father age will be only 6/7 of their total age . how old is the father now ?​

Answer 1

Answer: 55 years

Step-by-step explanation:

Let the father’s age be x. Then after 5 years his age will be x+5

Sum of the son’s age after 5 years is x+15 as there are three sons and 3x5=15.

So x+5 = 6/7(x+15)

7(x+5) = 6(x+15)

X= 55

Answer 2

Answer:let fathers age be careful

So total age of children is x

After five years

Father-x+5

Children-x+5+5+5

A/Q

7(x+5) =6(x+5+5+5)

7x+35=6x+30+30+30

7x-6x=90-35

X=55 yrs
