Answer»

Given, 7 oranges are bought for Rs. 3. Hence,

⇒The cost price of 1 oranges=Rs. 3/7

⇒And, the cost price of 100 oranges=$(Rs.\frac{3}{7} \times 100)$

= Rs. 300/7

Let the SELLING price of these 100 oranges be X.

We know that, Selling price = Cost price × (1 + Gain %)

Since the gain has to be 33%. THUS,

⇒Selling price for 100 oranges $(= \frac{{300}}{7} \times \left( {1 + \frac{{33}}{{100}}} \right))$

= Rs. 57

Hence, the oranges must be sold at a rate of Rs. 57 PER hundred.
