Answer 3

Calculation of Bread Consumption

To calculate the amount of bread consumed during dinner, we need to determine the quantity of bread consumed during breakfast and lunch.

Given: - Total bread consumed in the cafeteria in a day: 40 kg - Bread consumed during breakfast: 12 kg - Bread consumed during lunch: 3 kg more than breakfast

Let's calculate the bread consumed during lunch:

Bread consumed during lunch = Bread consumed during breakfast + 3 kg

Using the given information, we can calculate the bread consumed during lunch:

Bread consumed during lunch = 12 kg + 3 kg = 15 kg

To find the bread consumed during dinner, we subtract the sum of breakfast and lunch consumption from the total bread consumed in the cafeteria:

Bread consumed during dinner = Total bread consumed - (Bread consumed during breakfast + Bread consumed during lunch)

Substituting the values:

Bread consumed during dinner = 40 kg - (12 kg + 15 kg)

Calculating:

Bread consumed during dinner = 40 kg - 27 kg = 13 kg

Therefore, 13 kg of bread was consumed during dinner.
