Question

1)     Oranges are bought at 5 for Rs 10  and sold at 6 for Rs 15. Find profit or loss as percent.​

Answer 1

Answer:

Oranges are bought at 5 for Rs.10

Cost of 5 oranges is Rs.10  

So,cost of one orange =  

5

10

​  

=Rs.2

So the cost of 6 oranges=2×6=Rs.12

Cost of 6 oranges is Rs.12

Cost price=c.p=12

Selling Price=s.p=15

so profit =s.p−c.p=15−12=Rs.3

profit %=  

C.P

profit×100

​  

=  

12

3×100

​  

=25%

∴the profit % is 25%

Answer 2

Solution:-

Since, C.P of 5 oranges=RS 10

C.P of 1 orange= RS 10/5 = RS 2

Since, S.P of 6 oranges= RS 15

S.P of 1 orange=RS 15/6. = RS 2.5

Hence, gain= RS (2.5-2). = RS 0.5

And, gain percentage= 0.5/2×100 = 25%

Therefore, the profit percentage is 25%
