Question

A shopkeeper purchased bananas at ₹18 per dozen and sold 10 bananas at the the rate of ₹18. Find the gain or loss percent​

Answer 1

Step-by-step explanation:

To Find :

find the gain or loss percent

Solution:

Cost price of 1 dozen bananas = Rs.18

Cost price of 12 bananas = 18

Cost of 1 banana = \frac{18}{12}=1.5

12

18

=1.5

SP of 10 bananas = 18

SP of 1 Banana = \frac{18}{10}=1.8

10

18

=1.8

SP>CP

So, Profit

\begin{gathered}Profit\% = \frac{SP-CP}{CP}|times 100\\Profit\% = \frac{1.8-1.5}{1.5} \times 100\\Profit\%=20\%\end{gathered}

Profit%=

CP

SP−CP

∣times100

Profit%=

1.5

1.8−1.5

×100

Profit%=20%

Hence The gain% is 20%

Answer 2

Answer:

12 bananas are bought in =₹18

1banana is bought in =₹18/12=₹3/2

10bananas are bought in =₹15

10 bananas are sold in =₹18

therefore, CP=₹15

&SP=₹18

profit =SP-CP

₹18-₹15=₹3

profit %=SP-CP/CP×100=3/15×100=20%

Step-by-step explanation:

hence the shopkeepers profit is 20%
