An article was sold at 10% profit. If it had been sold at Rs 26 more than the selling price, the profit would have been 15%. The cost price of the article is:
ARs 480
BRs 500
CRs 510
DRs 520 ✓ Correct
Correct answer: (D) Rs 520 — The cost price of the article is Rs 520, so that is the answer.
Explanation
★The cost price of the article is Rs 520, so that is the answer.
★Let the cost price be x.
★At 10 percent profit the selling price is 110 percent of x.
★At 15 percent profit the selling price is 115 percent of x.
★The difference between these is 5 percent of x, which equals Rs 26.
★So x is 26 times 100 over 5, that is Rs 520.
