Question

After 15 years margies age will be four times of her present age what is her present age

Answer 1

Let her present age be x.
therefore after fifteen years the age would become 4x.

therefore x + 15 = 4x
therefore 3x = 15 and thus x = 5
therefore the present age of margie is 5 years

Answer 2

Let the present age be x
A/q,
=> x + 15 = 4x
=> 4x = x + 15
=> 3x = 15
=> x = 15/3
=> x = 5
Therefore, her present age is 5 years
