Answer 2

Answer:

the Present age is 5.

Step-by-step explanation:

Let say the present age is x.

so, after 15 years, he will be 4 times of his present age.

just write it mathematically,

=> x+15 = 4x

=> x = 4x-15

=> 0 = 4x-x-15

=> 0 = 3x -15

Rearranging

=> 3x - 15 = 0

=> 3x= 15

=> x= 15/3

=> x= 5

Result: Hence the current age is 5.

Hope this answer the question.
