Concept: The question tests on solving a word problem
Solution:
4 Large Cans = 6 Small Cans
1 Large Can = 1.5 Small Cans
4 sides of the house requires 24 small cans
So 1.5L + C = 24
Option 1: 1.5 * 2 + 24 = 27
Option 2: 1.5 * 4 + 18 = 6 + 18 = 24
Option 3: 1.5 * 6 + 16 = 9 + 16 = 25
Option 4: 1.5 * 8 + 8 = 12 + 8 = 20
Option 5: 1.5 * 12 + 12 = 18 + 12 = 30
Option B
