Question

A person buys 8 oranges for rs 15 and sells them at 10 for rs 18. What does he gain or lose percent?

Answer 1

SP is greater than the CP

Profit = 18-15= 3
So profit percent = Profit/CP *100
3/15*100=20%
So profit percent is 20%.

Answer 2

Answer:

Loss percent is 4 %

Step-by-step explanation:

C.P. of 8 oranges = rs 15

S.P. of 10 oranges = rs 18  

Let the number of oranges bought = LCM of ( 8 , 10 ) = 40

C.P of 1 orange = $\frac{15}{8}$

So, C.P. of 40 oranges = $\frac{15}{8}$ * 40

C.P. of 40 oranges = rs 75

Similarly,

S.P of 1 orange = $\frac{18}{10}$

So, S.P. of 40 oranges = $\frac{18}{10}$ * 40

S.P. of 40 oranges = rs 72

Since, C.P > S.P there will be a loss

Loss = C.P - S.P

Loss = 75 - 72

Loss = 3

Loss % = $\frac{Loss}{C.P}$ * 100

Loss % = $\frac{3}{75}$ * 100

Loss % = 4 %

Thus his loss percent is 4 %
