Mmatikoloi o na le dimaekrofono di le 50 tse a batlang go di rulaganya ka bobedi mo seraleng. Fa a ntse a di rulaganya, o lemoga gore 20% ya dimaekrofono ga di na go bona lefelo la go tsena morago ga go rulaganya tse dingwe ka bobedi.

Argo has 200 toys. He gives 40 toys to Alyssa, 80 to Bonnie, and 30 to Nicky. How many toys does Argo have now?
Palo ya dimaekrofono tse di sa kgonang go bona lefelo mo seraleng ke 20/100*50 = <<20/100*50=10>>10
Seno se raya gore mmatikoloi o kgonne go baya dimaekrofono di le 50-10 = <<50-10=40>>40 mo seraleng.
E re ka bobedi bo na le dimaekrofono di le 2, mmatikoloi o tlhomile bobedi jwa dimaekrofono di le 40/2 = <<40/2=20>>20 mo seraleng.
#### 20 

After Argo gives 40 toys to Alyssa, he remains with 200-40 =<<200-40=160>>160
Argo also gives 80 Bonnie 80 toys and remains with 160-80 = 80 toys
If he also gave Nicky 30 toys, the number of toys Arge remains with is 80-30 = <<80-30=50>>50.
