drop in the price of coat by 20 % results in a price of 0.8*112 (1-0.2=0.8)
subsequent 20% increase results in a price of 1.2 * 0.8 * 112 (1+0.2=1.2)
the final price is thus 0.96 *112 = 107.48 (i.e 96% of the original price implying a 4% decrease)
Answer to the question would be 100(1-0.96) i.e (E)
