ANSWER - 25 YEARS

Answer 2

Answer:

d). 25 years

The present age of A is 25 years

Step-by-step explanation:

Solution :

Present age of B = x

Present age of A = x + 15

After 5 years,

Age of B = x + 5

Age of A = x + 15 + 5 = x + 20

Also,

A's age will be double of B's age

So,

⇒ 2 (x + 5 ) = x + 20

⇒ 2x + 10 = x + 20

⇒ 2x - x = 20 - 10

⇒ x = 10

Present age of B = 10 years

Present age of A = x + 15

⇒ x + 15

⇒ 10 + 15

⇒ 25

Present age of A = 25 years

Therefore,

d). 25 years

The present age of A is 25 years
