(A) One day’s work of B is 1/10 - 1/15 (B) One day’s work of A and B is 1/10 and one day’s work of A is 1/15 (C) B alone can do the work in 30 days (D) One day’s work of B is 1/30 Correct Answer BADC

A and B together can do a piece of work in 10 days. If A can do the work in 15 days,

Step 1 = A’s one day work is 1/15 and One day work of A and B is 1/10,

Step 2 = One day work of B = One day work of A and B - One day work of A = 1/10 - 1/15

Step 3 = B’s one day work = 1/30

Step 4 = B alone can do the whole work in 30 days,

∴ Order is BADC.
