Question

help me please...,.......

Answer 1

Let her sister age be x
Then, anchal age = x + 12
After 4 years
Sister's age = x + 4
Anchal age = x + 12 + 4 = x + 16
So,
X + 16 = 3( x + 4)
X + 16 = 3x + 12
3x + 12 = x + 16
3x - x = 16 - 12
2x = 4
X = 4/2
X = 2
So, present age of sister = 2
And, anchal age = 2 + 12 = 14
Hope it helps...!!!
