Cole o ne a batla go reka di-jeans tse dintšhwa tsa mmino wa sethaba. Kwa lebenkelelong, o ne a sa kgone go tlhopha magareng ga di-jeans tse di gagogantsweng le di-jogger jeans. Ka ge di-jeans tseo di ne di le mo thekisong, o ne a swetsa ka go di reka tsotlhe. Di-jeans tse di gagogantsweng di ne di ja $28 fa di-jogger jeans di ne di ja $6 kwa tlase ga di-jeans tse di gagogantsweng.  O ne a bolokile $6 ka kakaretso. Fa a ne a bolokile 1/3 ya madi a a a bolokileng go tswa mo di-jogger jeans mme a mangwe a a a bolokile go tswa mo di-jeans tse di gagogantsweng, ke ka bokae di-jogger jeans di neng di ja bontsi jwa nako pele ga thekiso go feta di-jeans tse di gagogantsweng? 

There were 50 cats on a rock. Four boats came and carried away 5 cats each, and later, 3/5 of the remaining cats ran after a mouse they'd seen. How many cats were left on the rock?
Cole o ne a bolokile $6 x 1/3 = $<<6*1/3=2>>2 mo di-jogger jeans.
Ka jalo he, o ne a bolokile $6 - $2 = $<<6-2=4>>4 mo di-jeans tse di gagogantsweng.
Tlhwatlhwa ya ntlha ya di-jogger jeans ke $22 + $2 = $<<22+2=24>>24.
Cole o rekile di-jeans tse di gagogantsweng ka $<<28=28>>28
Ka jalo he, tlhwatlhwa ya ntlha ya di-jeans tse di gagogantsweng ke $28 + $4 = $<<28+4=32>>32.
Ka jalo he, di-jogger jeans di ne di ja bontsi jwa $32 - $24 = $<<32-24=8>>8 go feta di-jeans tse di gagogantsweng pele ga thekiso.

When four boats carried away 5 cats each, the total number of cats that left the rock is 4*5 = <<4*5=20>>20 cats.
The number of cats remaining on the rock became 50-20 = <<50-20=30>>30.
Later 3/5 of the remaining cats left the rock and ran after a mouse, a total of 3/5*30 = <<3/5*30=18>>18 cats.
The number of cats that remained on the rock is 30-18 = <<30-18=12>>12 cats
