Josh o ithaopile go tshameka motshameko wa go latlhela dibolo mo moyeng kwa 'talent show' kwa sekolong kgwedi e e tlang.  O simolola ka go ikatisa ka dibolo di le 3, mme ka bonya ka bonya a tokafala a oketsa bolo e le nngwe mo go tsa gagwe beke le beke. Morago ga beke ya bone 'talent show' e a simolola, mme fa Josh a tsena mo seraleng o a relela mme a latlhegela dibolo di le 3.  Tse 2 di kgona go tshwarwa ke batho mo bokopanong fa di ntse di kgokologela kwa ntle ga serala, mme e le nngwe ya latlhega gotlhelele ka ntlha ya lefifi mo holong. Ka go hethemola, Josh o simolola go tshameka ka dibolo di le kae? 

A class of 200 students is split into 3 groups such that 2 of them are equal in number and the last one (which is the smallest) is 10 less than each of the other groups. How many students are in this (smallest) group?
Josh o simolola ka dibolo di le 3 mme a oketsa e le nngwe beke le beke go fitlha di le 3+4=<<3+4=7>>7
Josh o latlhegetswe ke dibolo di le 3 fa a relela mo seraleng mme tsa sala e le 7-3= <<7-3=4>>4 
#### 4 

If 10 is added to the smallest group (hence to the total number of students), it would make all 3 groups equal to give (200+10)/3 = <<(200+10)/3=70>>70 in each group.
Now taking the 10 away from one group gives the number of the smallest group as 70-10 = <<70-10=60>>60 students.
