Official Solution: TetyanaRokobit
On a particular day, three brothers, Larry, Garry, and Barry each pick apples for five hours at a constant rate of at least one apple per hour. Barry picks apples three times faster than does Larry, and half as fast as Garry does.
In the table, select for 'Apples picked per Hour by Garry' a possible number of apples picked per hour by Garry and select for 'Total apples picked by Barry' a possible number of total apples picked by Barry that would be jointly consistent with the given information. Make only two selections, one in each column.
Yes No
Once the number of apples picked by Barry is determined to be 30, it is known that Barry's rate of apple picking is 6 apples per hour. Since Barry's rate is half that of Garry's, it is known that Garry picks 12 apples per hour.
Corrected answers:
Yes: 12 No: 13
