**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**
