Think Kritika present age be x
Then her age four year back will be x-4
Let Kritika age after 12 years be x+12
By this we can equate
X+12=(X-4)4
X+12=4X-16
Transpose similar terms to one side
16+12=4X-X
Hence 3X=28
X=28/3
Then her age four year back will be x-4
Let Kritika age after 12 years be x+12
By this we can equate
X+12=(X-4)4
X+12=4X-16
Transpose similar terms to one side
16+12=4X-X
Hence 3X=28
X=28/3
