Question

If I would have purchased 11 articles for Rs.10 and sold all the 10 articles at the rate of Rs.11, the profit percent would have been :

• A. 10%
• B. 11%
• C. 21%
• D. 100%

Answer 1

Answer:

C. 21%

11 articles for Rs.10 CP of 1 article = 10/11

Sold 10 articles for Rs.11 SP of 1 article = 11/10

Profit% = SP-CP/CP x 100

$=\frac{\frac{11}{10}-\frac{10}{11}}{\frac{10}{11}}\times{100}$

$=\frac{\frac{121-100}{110}}{\frac{10}{11}}\times{100}$

$=\frac{21}{110}\times{\frac{11}{10}}\times{100}$

= 21%
