SSC CPO 12th-March-2019-Shift-1

- The ratio of efficiencies of A, B, and C is 4:5:6. This means A completes 4 units of work, B completes 5, and C completes 6 per day.

- Together, they complete 4 + 5 + 6 = 15 units in one day.

- They finish the entire work in 12 days by working together.

- Total work = 15 units/day * 12 days = 180 units.

- A's efficiency is 4 units/day.

- Therefore, A will complete the work alone in 180 units / 4 units/day = 45 days.

Option 2: 45 days is correct.
