II. The expected crop is 13,500 litres

Option A:

Option B:

Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked.

Option C:

BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient to answer the question asked.

Easy

### Solution

Option C is the correct answer.

### Option Analysis

Statement I is insufficient: A workday yield is 45 litres Insufficient: We don’t know the total volume of crop to be picked

Statement II is insufficient: The expected crop is 13,500 litres Insufficient: We don’t know the rate i.e. workday yield per worker.

Together I and II, Sufficient:

Number of workers = (total crop volume)/(yield per day * number of days) N=13500(45)∗(15)=20
