Question

The sum of the ages of a and B is 50 years. 5 years ago A was 7 times the age of B and what is the present age of A and B today?
​

Answer 1

Answer:

The present age of A and B are 40years and 10years respectively.

Step-by-step explanation:

let, 5 years ago B's age was x years.

then A's age was 7x years.

now, conditionally,

(7x+5)+(x+5)=50

or, 8x=50-10

or, x= 40/8

or, x=5

now ,B's age is (5+5)years i.e. 10yrs.

and A's age is (50-10)years i.e. 40 yrs.
