<human>:  Gumball was counting his water intake for the previous week. He checked his list and saw that he had drank 60 liters of water for the week. He drank nine liters of water on Monday, Thursday and Saturday and 8 liters of water on Tuesday, Friday and Sunday. Unfortunately, no data was input on Wednesday. How many liters of water did he drink on Wednesday?
<bot>: How many liters of water did Gumball drink on Monday, Thursday, and Saturday? ** Gumball's total water intake on Monday, Thursday, and Saturday is 9 x 3 = <<9*3=27>>27 liters.
How many liters of water did Gumball drink on Tuesday, Friday, and Sunday? ** And his total water intake on Tuesday, Friday, and Sunday is 8 x 3 = <<8*3=24>>24 liters.
How many liters of water did Gumball drink in total? ** So his total water intake for 6 days is 24 + 27 = <<24+27=51>>51 liters.
How many liters of water did Gumball drink on Wednesday? ** Therefore Gumball's water intake on Wednesday is 60 - 51 = <<60-51=9>>9 liters.
