Question

After 12 years, Kritika will be 4 times as old as she was 4 years ago. Find her present age. ​

Answer 1

present age of Kritika = x

kritika's age after 12 years==>

x + 12 = 4 ( x - 4 )

x + 12 = 4x - 16

x - 4x = -16 - 12

-3x = -28

3x = 28

x = 28/3 = 9.3 years

the present age of Kritika is 9.3 years

Answer 2

Answer:

9 years and 3 months old

Step-by-step explanation:

Let the present age of Kritika be x

Kritika's age after 12 years will be x + 12

Kritika's age before 4 years would be x - 4

x + 12 = 4 ( x - 4 )

x + 12 = 4x - 16

12 + 16 = 4x - x

28 = 3x

x = 28/3 = 9.3 years

∴ The present age of Kritika is 9 years and 3 months
