Koloi ya ga Mark e ile ya senyega mme o tlhoka go reka radiator e ntšha.  Radiator e ntšha e ja $400 mme o e rekile kwa marekisetsong a dikoloi tse di senyegileng ka theko e e kwa tlase ka 80%.  Morago ga foo o ne a hira mekaniki go e tsenya mme a bereka diura di le 3 ka $50 ka ura. O duetse bokae?

John had a son James when he was 19.  James is now twice as old as his sister Dora, who will turn 12 in 3 years.  How old will John's youngest son, who was born when John was 32, be in 3 years?
Theolelo ya radiator e ne e le 400*.8=$<<400*.8=320>>320
Ka jalo o duetse 400-320=$<<400-320=80>>80
Mekhaniki o mo lefeditse 3*50=$<<3*50=150>>150
Ka jalo botlalo jwa se a se dueletseng ke 80+150=$<<80+150=230>>230
#### 230 

Dora is 12-3=<<12-3=9>>9
So James is 9*2=<<9*2=18>>18 years old
That means John is 18+19=<<18+19=37>>37
Johns youngest son is 37-32=<<37-32=5>>5 years old
So he will be 5+3=<<5+3=8>>8 in 3 years
