Question

A shopkeeper buys candies at 9 for Rs10 and sells the candies at 6 for Rs10. What is his profit per cent?​

Answer 1

Step-by-step explanation:

9+6=15

10+10=20

15-20=5

profit percentage= 5×100/20=25%

Answer 2

Cost Price :

Of 9 candies = 10 RS

Of 1 candy =

$\frac{10}{9} \: rs$

Selling Price :

Of 6 candies = 6 RS

Of 1 candy =

$\frac{10}{6} \: rs$

This is profit....

Profit Percentage :

$= \frac{sp-cp}{cp} \times 100 \\ = \frac{\frac{10}{6}-\frac{10}{9} }{\frac{10}{9} } \times 100 \\ = \frac{\frac{60-40}{36}}{\frac{10} {9}} \times 100 \\ = \frac{\frac{20}{4}}{\frac{10} {1}} \times 100 \\ = \frac{1}{2} \times 100 \\ = 50\%$
