Question

seema is 20 years old and reema is 4 years old.in how many years will seema be twice as old as reema

Answer 1

Age of Seema = 20 yrs
Age of Reema = 4 yrs

Let the number of years after which Seema will be twice as old as Reema be 'x'.

(20 + x) = 2(4 + x)
20 + x = 8 + 2x
20 - 8 = 2x - x
12 = x

Therefore, Seema will be twice as old as Reema after 12 years.

Answer 2

Age of Seema = 20 yrs

Age of Reema = 4 yrs

Let the number of years after which Seema will be twice as old as Reema be 'x'.

Then the equation we get:

20 + x = 2(4 + x)

20 + x = 8 + 2x

x - 2x = 8 - 20

- x = - 12

x = 12 years

Therefore, Seema will be twice as old as Reema after 12 years.
