- The efficiencies of A, B, and C are in the ratio 5:6:8.

- Together, A, B, and C can finish the work in 120 hours.

- Calculate the total work: The combined efficiency ratio is 5+6+8 = 19.

- Thus, total work = 19 * 120 = 2280 units.

- B's efficiency is part of the ratio, which is 6.

- So, B can do 6 units of work per hour.

- Calculate 40% of the work: 40% of 2280 = 912 units.

- Determine time for B to complete 912 units: 912 / 6 = 152 hours.

- Correct Answer: Option 1: 152
