Answer 3

Calculating the Cost of Cucumbers and Tomatoes

To calculate the cost of cucumbers and tomatoes separately, we can use the following approach:

1. Let's assume the cost per kilogram of cucumbers and tomatoes is x. 2. The total cost of 7 kg of cucumbers is 7x. 3. The total cost of 3 kg of tomatoes is 3x. 4. Given that the cost of tomatoes is 40 d.e. less than the cost of cucumbers, we can form the equation: 7x - 3x = 40.

Calculating the Cost

To find the value of x and subsequently the cost of cucumbers and tomatoes, we can solve the equation:

7x - 3x = 40

Solving for x: 4x = 40 x = 40 / 4 x = 10

Now that we have the value of x, we can calculate the cost of cucumbers and tomatoes separately:

- Cost of 7 kg of cucumbers = 7 * 10 = 70 d.e. - Cost of 3 kg of tomatoes = 3 * 10 = 30 d.e.

So, the mother paid 70 d.e. for cucumbers and 30 d.e. for tomatoes.
