Solution

Let us consider the problem.
Original price is Rs x per. kg.
New price is Rs 1.12x
since, Dealer gets 27kg. less for Rs. 24750 at new price.
hence,
247501.12x+27=24750x
(24750+30.2x1.12x)=24750x
24750+30.4x=24750×1.12
30.24x=2772024750
hence,
x=297030.24=98.21
There fore new price is Rs 98.21×1.12= Rs. 110
