Cost of chocolate = Rs 125 Cost of candy = Rs 165 |
Check the solution below:
The candy costs Rs 40 more than the chocolate.
Let us assume the cost of the chocolate to be x.
Then the cost of the candy= y = Rs 40 + x
The cost of 3 chocolates = 3 × x = 3x and the cost of 2 candies = 2y = 2(40 + x)
Total cost of 2 candies and 3 chocolates= Rs705
Therefore, Rs 2y + 3x = Rs 705
2(40 + x) + 3x = 705
80 + 2x + 3x = 705
80 + 5x = 705
5x = 705 – 80
5x = 625/5
x = 125 and 40 + x = 40 + 125 = 165
Therefore, the cost of each chocolate is Rs 125 and that of each candy is Rs 165.
