Question

If by selling $110$ mangoes, the CP of $120$ mangoes is realised, then the gain per cent is

• A. $9\frac{1}{11}\%$
• B. $9\frac{1}{9}\%$
• C. $10\frac{10}{11}\%$
• D. $11\frac{1}{9}\%$

Answer 1

The correct option is A $9\frac{1}{11}\%$

Let CP of 1 mango $=Re.1$
CP of 110 mangoes $=Rs.110$
SP of 110 mangoes = CP of 120 angoes $=Rs.120$
Gain $=120-110=Rs.10$
Thus, Gain % $=\frac{Gain}{CP}\times 100=\frac{10}{110}\times 100$
Gain % $=9\frac{1}{11}\%$
