Question

Helen delivers parcels.
On Tuesday, Helen delivered 20% more parcels than on Monday.
On Wednesday, Helen delivered 50% fewer parcels than on Tuesday.
On Wednesday, Helen delivered 72 parcels.

Answer 1

Step-by-step explanation:

on Monday let it be X parcel delivered....

X + 20% - 50% + 32 = 100%

x -30% + 32 = 100%

x + 32 = 100% + 30%

x = 130% -32

x = 130/100 - 3200/100

= - 3070
