Question

29. After 12 years, Mamta shall be 3 times as old as she was 4 years ago. Find her present age​

Answer 1

Let the present age of Kamal be X.

After 12 years,

kamal’s age(X+12) will be 3 times as old as he was 4 years ago[3(X-4)]

i.e.

X+12=3(X-4)

X+12=3X-12

2X=24

X=12.

Hence Kamal’s present age is 12.
