Answer 2

Calculating the Amount of Paper Collected by Class 5-V

To calculate the amount of paper collected by class 5-V, we'll start by finding the amounts collected by classes 5-A and 5-B. Then, we'll subtract those amounts from the total to find the amount collected by class 5-V.

Given: - Total paper collected: 400 kg - Class 5-A collected: 32% - Class 5-B collected: 28%

Calculation Steps:

1. Calculate the amount collected by class 5-A: - 32% of 400 kg = 0.32 * 400 kg = 128 kg

2. Calculate the amount collected by class 5-B: - 28% of 400 kg = 0.28 * 400 kg = 112 kg

3. Calculate the amount collected by class 5-V: - Total collected = 400 kg - Amount collected by class 5-A = 128 kg - Amount collected by class 5-B = 112 kg - Amount collected by class 5-V = Total collected - (Amount collected by class 5-A + Amount collected by class 5-B) - Amount collected by class 5-V = 400 kg - (128 kg + 112 kg) = 400 kg - 240 kg = 160 kg

Answer:

The students of class 5-V collected 160 kilograms of paper.
