1.	After 15 years, Hema’s age will become four times that of her present age. Find her present age.
Answer» Let the present age of Hema be x years After 15 years Hema Age = 4x By problem, x + 15 = 4x x + 15 – 4x = 4x – 4x (Subtracting 4x from both sides) – 3x + 15 = 0 – 3x = – 15 x = -15/-3 transposing x ( – 3)] x = 5 ∴ Her present age is 5 years. ∴ Her present age is 5 years.

Answer»

Let the present age of Hema be x years

After 15 years Hema Age = 4x

By problem, x + 15 = 4x

x + 15 – 4x = 4x – 4x (Subtracting 4x from both sides)

– 3x + 15 = 0

– 3x = – 15

x = -15/-3 transposing x ( – 3)]

x = 5

∴ Her present age is 5 years.
