A farmer who grows strawberries defines . . .

[M7MBA]

A farmer who grows strawberries defines a "workday yield" as the number of liters of strawberries that a worker is required to pick in one day. Based on this definition, how many workers must the farmer hire to pick the entire expected crop of strawberries in 15 calendar days?

(1) A workday yield is 45 liters
(2) The expected crop is 13,500 liters

C is the OA.

I don't have this question clear. May any expert give me a detailed explanation here? Thanks in advanced.

A farmer who grows strawberries defines a "workday yield" as the number of liters of strawberries that a worker is required to pick in one day. Based on this definition, how many workers must the farmer hire to pick the entire expected crop of strawberries in 15 calendar days?

(1) A workday yield is 45 liters
(2) The expected crop is 13,500 liters

Statement 1:
Since the size of the crop is unknown, we cannot determine how many workers must be hired for the crop to be picked in 15 days.
INSUFFICIENT.

Statement 2:
For 13,500 liters to be picked in 15 days, the amount that must be picked each day = 13,500/15 = 900 liters.
Since the rate for each worker is unknown, we cannot determine how many workers must be hired for 900 liters to be picked each day.

Statements combined:
Required number of workers = (required daily yield)/(daily rate for each worker) = 900/45 = 20.
SUFFICIENT.

The correct answer is C.
