If toffees are bought at the rate of 7 for Rs. 6, at what rate per hundred must they be sold to gain 33%?114115118120None

First, let's find out the cost price of 1 toffee. If 7 toffees are bought for Rs. 6, then 1 toffee is bought for Rs. 6/7.

Next, we need to calculate the selling price for 1 toffee to gain a profit of 33%. The formula to calculate the selling price is: Selling Price = Cost Price + (Profit% of Cost Price).

So, the selling price for 1 toffee = Rs. 6/7 + (33/100 * 6/7) = Rs. 6/7 + Rs. 2/7 = Rs. 8/7.

Now, we need to find out the selling price per hundred toffees. If 1 toffee is sold for Rs. 8/7, then 100 toffees will be sold for Rs. 8/7 * 100 = Rs. 114.29.

So, the toffees must be sold at the rate of approximately Rs. 114 per hundred to gain a profit of 33%. Therefore, the answer is None of the above.
