Let x be the original price
after 20% decrease, new price = 0.8x
after 15% further decrease = 0.8x*.85=0.68x
coat’s summer price is what percent of its original price = 0.68x/x = 0.68 = 68%

Hence Option D is correct.

Let original price be 100

Reduced price of coat is 80

Final reduced price is \(\frac{80*(100-15)}{100} = 68\)

Thus, the final price of the coat is \(\frac{68}{100*100}\) = 68% of the Original Price.

Hence, answer will be (D) 68%

B. 64%

E. 80%



We can let the original price of the coat = x. After a 20% reduction, the price is 0.8x. After another 15% reduction, the price is 0.85(0.8x) = 0.68x.

Thus, coat’s summer price is (0.68x/x)100 = 68% of the original price.

Answer: D
