Question

1) The selling price of a ten pencil is equal to the cost price of 11 pencil . find the gain prrcent

Answer 1

answer

SP of 10 pencils=CP of 11 pencils
Let CP of each pencil be rs.1
So, CP of 10 pencils=rs.10
SP of 10 pencils=rs.11
SP is greater than CP
So, there is a profit.
Profit=11-10=rs.1
Profit per cent= (1/10*100)per cent=10 per cent
