# Jusum buys some chocolates at the rate of Rs. 10 per chocolate. She also buys an equal number of candies at the rate of 5 per candy. She makes a 20% profit on chocolates and 8% profit on candies. At the end of the day, all chocolates and candies are sold out and her profit is Rs. 240. Find the number of chocolates purchased.

Answer :

Let Jusum purchased x chocolates

Total cost of chocolates = Rs. 10x

Similarly, she purchased x candies

Total cost of candies = Rs.5x

According to the question

Profit on chocolates = 20% of 10x = 20/100 × 10x = Rs. 2x

Profit on candies = 8% of 5x = 8/100 × 5x = Rs. 0.4x

∴Total profit = 2x + 0.4x = Rs. 2.4x

But it is given that total profit is Rs. 240

According to the question

2.4x = 240

x = 100

(divide by 2.4 on both the sides)

Hence she purchased 100 chocolates
