Question

25. After 15 years, Sheela's age will become 4 times that of her present age. Her present age is
(a) 5 years
(c) 7 years
(b) 9 years
(d) None of these​

Answer 1

Let Sheela's present age be x years.

After 15 years,her age will be (x+15) year.

according to the question ,

4x=x+15

4x−x=15

3x=15

x=5

hence Sheela's present age is 5 years.

Answer 2

Answer:

Let Sheela's present age be X

Then we have to make a equation and then we have to sove it .

x = 4x + 15

4x-x = 15

3x = 15

x = 15÷3

x = 5

So Sheela's present age = x and x is 5 so her present age = 5 years .
