Gore a bone lotseno la P2000, Isaias o tshwanetse go rekisa koko e a ikaeletseng go e isa kwa mmarakeng go tswa kwa polaseng ya gagwe ka P50 koko nngwe le nngwe. Fa Isaias a na le dikoko di le 300 kwa polaseng ya gagwe mme a ikaeletse go rekisa 3/5 ya tsona, o rekile dikoko tse a di isitseng kwa mmarakeng ka madi a makae?

Paul has 52 marbles. His friend gave him 28 marbles. Then, he lost 1/4 of his marbles. How many marbles does Paul have left?
Isaias o ikaeletse go rekisa 3/5*300 = <<3/5*300=180>>180 ya dikoko go tswa kwa polaseng ya gagwe.
Gore a bone lotseno la gagwe, Isaias o rekisa dikoko tsotlhe tse a di isitseng kwa mmarakeng ka P50*180 = P<<50*180=9000>>9000.
Tlhwatlhwa e Isaias a rekileng dikoko ka yona ke P9000-P2000 = P<<9000-2000=7000>>7000. 
#### 7000 

Paul has a total of 52 + 28 = <<52+28=80>>80 marbles.
He lost 1/4 x 80 = <<80/4=20>>20 marbles.
Therefore, he has 80 - 20 = <<80-20=60>>60 marbles left.
#### 60
