Question

if 11 oranges are bought for rs.10 and sold at 10 for rs.11 what is the gain or loss percentage

Answer 1

Hiii...
Here is your answer...

Solution:-
CP of 11 oranges are₹10
So,CP of 1 orange=
$= > \frac{10}{11}$
SP of 10 oranges are ₹11
So,SP of 1 orange=
$= > \frac{11}{10}$
Since,
$\frac{11}{10} > \frac{10}{11}$
SP>CP

So,
Gain=SP-CP
$= > \frac{11}{10} - \frac{10}{11} \\ = > \frac{121 - 100}{110} \\ = > \frac{21}{110}$
Now,
$gain\% = \frac{gain}{cp} \times 100$
$= > \frac{ \frac{21}{110} }{ \frac{10}{11} } \times 100$
$= > \frac{21}{110} \times \frac{11}{10} \times 100$
$= > 21$
Hence,he gain 21℅

Answer 2

Answer:

21%

Step-by-step explanation:

Cost of 11 oranges = Rs.10

Cost of 1 orange = $\frac{10}{11}$

Selling price of 10 oranges = Rs.11

Selling price of 1 orange = $\frac{11}{10}$

SP>CP

So,Gain%=$\frac{SP-CP}{CP} \times 100$

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

Gain%=$21\%$

Hence his gain% is 21%
