Problem Analysis

To solve this problem, we need to determine the amount of blue paint, the total amount of paint, and the amount of paint remaining after 90 kg has been used. We are given that 128 kg of white paint was brought, which is 45 kg more than the blue paint. Let's solve each part of the problem step by step.

Solution

a) To find the amount of blue paint, we need to subtract 45 kg from the total amount of white paint brought. Therefore, the amount of blue paint is 128 kg - 45 kg = 83 kg.

b) To find the total amount of paint, we need to add the amount of white paint and the amount of blue paint. Therefore, the total amount of paint is 128 kg + 83 kg = 211 kg.

c) To find the amount of paint remaining, we need to subtract the amount of paint used (90 kg) from the total amount of paint. Therefore, the amount of paint remaining is 211 kg - 90 kg = 121 kg.

Summary

a) The amount of blue paint is 83 kg. b) The total amount of paint is 211 kg. c) The amount of paint remaining is 121 kg.
