A painter is hired to paint a wall with a special shade. To prepare the paint, he mixes red, blue, and white in the ratio 4 : 2 : 1. For this design, he prepares 14 liters of paint in total. How many liters of white paint does he use?
Show answer & explanation
Correct answer: B
Explanation
Given:
Red : Blue : White = 4 : 2 : 1
Total paint = 14 L
According to the formula:
One part = Total quantity / Total ratio
Total ratio = 4 + 2 + 1 = 7
One part = 14 / 7 = 2 L
White paint = 1 × 2 = 2 L
