Question

a persons age after 15 years will be four times his age 15 years back. What is his present age​

Answer 1

Answer:

Let the person's present age be x

According to the question,

x+15 = 4(x-15)

x+15 = 4x-60

15+60 = 4x-x

3x = 75

x = 25

His present age is 25 years.

Answer 2

Answer:

25 years

Step-by-step explanation:

Let his present age be x years

We have been given here that

x +15 = 4( x-15)

so, x+15 = 4x -60

or, 60 + 15 = 4x - x

therefore, 75 = 3x

Hence x = 25.

Therefore the person now is of 25 years.
