Option 4 : All the statements are required to answer the question.

Statement I and II:

Suppose the total amount of work = 30 units (LCM of 15 & 10)

∴ Efficiency of C = 30/15 = 2

Efficiency of (A + B) = 30/10 = 3

Statement III:

∵ The time taken by A is equal to the time taken by B and C together;

∴ Efficiency of A = Efficiency of (B + C)

Combining all three statements∶

Efficiency of A = 2.5 and Efficiency of B = 0.5

∴ Time taken by B to complete the job = 30/0.5 = 60 days

∴ All the statements are required to answer the question.
