Define their percentage:
----------------------------------
Adam = 100%
Tapiwa = 100 + 5 = 105%
----------------------------------
Find their total percentage:
----------------------------------
100 + 105 = 205
----------------------------------
Find 1%
----------------------------------
205% = 697 liters
1% = 3.4 liters
----------------------------------
Find 100% (Adam):
----------------------------------
100% = 3.4 x 100
100% = 340 liters
----------------------------------
Find 105% (Tapiwa):
----------------------------------
105% = 3.4 x 105
105% = 357 liters
--------------------------------------------------------------------
Answer: Tapiwa = 357 liters and Adam = 340 liters.
