Question

A person by selling an article for Rs. 180 loses 10%. In order to make a profit of $10\%$ at what price he must sell?

• A. Rs. 210
• B. Rs. 220
• C. Rs. 200
• D. Rs. 230

Answer 1

Answer: (B)

Rs. 220

Given, Loss $=10$ %

$=>\frac{CP-SP}{CP}\times 100=10$

$=>\frac{CP-180}{CP}\times 100=10$

$=>CP-180=0.1CP$

$=>0.9CP=180$

$=>CP=200$
To make a profit of $10$ %, he must sell it at $SP=CP+10$ % of $CP$ $=200+20=Rs.220$
