Answer 2

Answer:

Ratio of ages of A and B = 5 : 8

Step-by-step explanation:

Present age of A = 28 years

Present age of B = 49 years

After 7 years-

New age of A = 28 + 7

Age of A = 35 years

New age of B = 49 + 7

Age of B = 56 years

Ratio of ages of A and B = $\dfrac{Age of A}{Age of B}$

                                       = $\dfrac{35}{56}$

                                       = $\dfrac{5}{8}$

Ratio of ages of A and B = 5 : 8
