Number of parcels on Mondays, Wednesdays and Fridays is the same.
Total number of parcels = 15
Hence, plot 1 meets all the conditions of the delivery.
Plot 2:

Number of parcels on Mondays, Wednesdays and Fridays is the same.
Total number of parcels = 17
Hence, plot 2 does not meet all the conditions of the delivery.
Plot 3:

Number of parcels on Mondays, Wednesdays and Fridays is the same.
Total number of parcels = 13

Number of parcels on Mondays, Wednesdays and Fridays is the same.
Total number of parcels = 12
Hence, plot 4 does not meet all the conditions of the delivery.
Therefore, the only plot that meets all the conditions of the delivery is plot 1.
