Question

Y is older than x by 7 years. 15 years back x's age was 3/4 of y's age. Their present ages?

Answer 1

Step-by-step explanation:

Let the age of X be "a" years

yhen age of Y will be "a+7" years

Now ,

ATQ,

a - 15 = 3/4 of a +7 -15

a - 15 = 3/4 of a -8

a - 15 = (3a - 24) /4

4a - 60 = 3a -24

4a - 3a = - 24 + 60

a =. + 36.

Hence age of X is 36 years and age of Y is 43 years
