Box Weight | MCQs

Explanation

We are given:

• 4 boxes with weights: 20 kg, 30 kg, 50 kg, and 70 kg.

We need to determine which total weight cannot be made by combining these boxes.

Let's check the combinations:

1. 20 + 30 + 50 + 70 = 170 kg
2. 20 + 30 + 50 = 100 kg
3. 20 + 30 + 70 = 120 kg
4. 20 + 50 + 70 = 140 kg
5. 30 + 50 + 70 = 150 kg

Now check if 160 kg can be made:

• The possible combinations do not result in 160 kg.

Explanation

We are given:

Total weight of 5 boxes with soup = 75 kg

Weight of each empty box = 3 kg

Step 1: Calculate the total weight of empty boxes

Since there are 5 boxes and each empty box weighs 3 kg:

5 boxes×3 kg=15 kg (total box weight)

Step 2: Subtract the empty box weight from the total weight

75 kg (total)−15 kg (boxes)=60 kg (soup only)
