Andy o tlhometse dithunya tsa geraniums dile 90 mme a tlhome tsa petunias di le kwa tlase ga tsa  geraniums ka di le 40. Ke dithunya di le kae tse a di tlhomileng kaofela? 

A water tank is filled with 120 liters of water. Celine used 90 liters of water from the tank to water her small garden. She was then able to collect rainwater that is twice as much as what was left. How many liters of water are in the tank now?
Sa ntlha bona palo ya dithunya tsa petunias tse Andy a di tlhomileng: 90 dithunya - 40 = <<90-40=50>>50 dithunya
Morago ga foo, tshwara palo ya mofuta mongwe le mongwe wa dithunya tse a di tlhomileng go bona palo yotlhe: 50 dithunya + 90 dithunya = <<50+90=140>>140 dithunya
#### 140

After watering Celine's garden, 120 - 90 = <<120-90=30>>30 liters of water were left in the tank.
Celine was able to collect 30 x 2 = <<30*2=60>>60 liters of rainwater.
Thus, there are 30 + 60 = <<30+60=90>>90 liters of water in the tank.
