# 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.

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
