Let the price of car before increase in price was X. Increase of 12% shall be X x 12/100. Sum of both shall be:
X + (X x 12/100) = 96320
X + 3X/25 = 96320
[X/1 + 3X/25 = (25X + 3X)/25 = 28X/25]
28X/25 = 96320
X = (96320 x 25)/28 = Rs.86000

can u tell from where does this 28 appear in 3rd line ???
Dear Aslam, I have edited the above reply and shown there how two fractions are added by taking LCM. [X/1 + 3X/25 = (25X + 3X)/25 = 28X/25].
