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


According to question,

4(x) = ( x + 15)
4x - x = 15
3x = 15
x = 5

Therefore, Hema's present age is 5 years.

Answer 2

Answer:

Hema's present age is 5 years,  if after 15 years her age would be four times the age of her present age.

Explanation:

Let Hema's be X years.

∴ After 15years,

Hema's age = X + 15 years = 4X years.

X + 15 = 4x years.

15 = (4x - x) years

15 = 3x years

X = 5 years

Answer) Hema's present age thus will be 5years.
