Question

6 Kusum buys some chocolates at the rate of 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
240. Find the number of chocolates purchased.​

Answer 1

Answer:

Solution

Let Kusum purchased x chocolates.

Then, total cost of chocolates=Rs. 10x

Similarly, she purchased x candies.

Then, total cost of candies=Rs.5x

According to the question,

Profit on chocolates = 20% of 10x=

20

2x10x = Rs.2x

100

and profit on candies=8% of 5x=

8

100

x 5x = Rs. 0.4x

Total profit =2x+0.4x=Rs.2.4x

But it is given that total profit is Rs. 240.

Again, according to the question, 240_ 2.4x = 240 → x = = 100

2.4

Hence, he purchased 100 chocolates.
