Question

A dealer buys an article listed at Rs 100 and gets successive discounts of 10% and 20%. He spends 10% of the cost price on transport. At what price should he sell the article to earn a profit of 15% ? 

(a) Rs 90

(b) Rs 90.02 

(c) Rs 91.08 

(d) Rs 91.28

Answer 1

(c) Rs 91.08

Cost price of the article after discount = 90% of 80% of Rs 100

= \(\frac{90}{100}\) x \(\frac{80}{100}\) x Rs 100 = Rs 72

Amount spent on transport = 10% of Rs 72

\(\therefore\) Net C.P. = Rs 72 + Rs 7.20 = Rs 79.20 Profit = 15%

\(\therefore\) S.P. = Rs \(\big(\frac{79.2\times115}{100}\big)\)= Rs 91.08
