Question

the ratio between the age of the father and son is 5:2 if 7 years ago the father age was 43 years old what is the present age of sun​

Answer 1

Answer:

the present age of son is 20 years

Answer 2

Answer:

Suppose that

In present, the age of son =X

According to question,

Age of her father:age of son::5:2

Writing in fraction form,

Age of her father/age of son=5/2

The age of her father=5 xage of son/2

Age of her father 5x/2

Seven years ago, the age of her father =present age

-7

The age of her father was=(5x/2)-7

Given that 7 years ago the age of her father was 43

So

(5x/2)-7=43

(5x/2)=50

5x 100

x=20

Hence the age of the son is 20years
