Question

a vendor buys 8 oranges at rs 15 and sell them at 10 for rs 18 .What is his gain or loss per cent?

Answer 1

Hii...
Here is your answer...

Solution:-
CP of 8 orange is ₹15
So,CP of 1 orange=
$= > \frac{15}{8}$
Now,
SP of 10 orange is ₹18
So,SP of 1 orange=
$= > \frac{18}{10} = \frac{9}{5}$
Since,
$\frac{15}{8} > \frac{9}{5}$
CP>SP

Therefore,
Loss=CP-SP
$= > \frac{15}{8} - \frac{9}{5} \\ = > \frac{75 - 72}{40} \\ = > \frac{3}{40}$
Now,
$loss\% = \frac{loss}{cp} \times 100$
$= > \frac{ \frac{3}{40} }{ \frac{15}{8} } \times 100$
$= > \frac{3}{40} \times \frac{8}{15} \times 100$
$= > \frac{20}{5} = 5$
Hence,he loss 5℅

Hope it helps uh....✌️✌️✌️
