Question 01
A vendor bought 6 toffees for a rupee. How many for a rupee must he sell to gain 20% ?
Given
CP of 6 toffees = ₹1
So, CP of 1 toffee = ₹ 1/6
According to question,
The vendor should profit = 20%
Formula Used
We know that,
SP = CP(100+gain%)/100
=(1/6)*(100+20) / 100 ==> ₹ 1/5
Hence in order to get 20% profit, the vendor should sell one toffee at 1/5 rs
