​

Answer 1

Answer:

Step-by-step explanation:

let A's age be 3x and B's age be 7x

According to the ques:

7x - 3x  = 16

4x = 16

x = 16/4

x = 4

B's age = 7x

            = 7 (4)

            = 28 years

Answer 2

So here is the answer

Let the age of A be 3x

And B be 7x

A/q

7x-3x=16

4x=16

x=16/4

x=4

so B age is 7x

Then 7×4= 28 yrs
