Read Explanation:
Solution:
Given:
C alone can complete two-third part of a work in 12 days
Concept:
If a person can complete (x/y) part of a work in z days, then the person can complete the whole work in {z × (y/x)} days
Calculation:
2/3 part → 12 days
⇒ 1 part → 12 × (3/2) = 18 days
∴ C can complete the whole work in 18 days
