### Instruction:
 Kwa kila bata mweupe kwenye ziwa kuna samaki 5. Kwa kila bata mweusi kuna samaki 10 na kwa kila bata mchanganyiko kuna samaki 12. Kwa sasa kuna bata 3 weupe, bata 7 weusi na bata 6 wachanganyiko. Kuna samaki wangapi kwenye ziwa?


### Response:
 Bata weupe: bata 3 * samaki 5/bata = <<3*5=15>>15 samaki
Bata weusi: bata 7 * samaki 10/bata = <<7*10=70>>70 samaki
Bata wachanganyiko: bata 6 * samaki 12/bata = <<6*12=72>>72 samaki
Jumla: 15 samaki + 70 samaki + 72 samaki = <<15+70+72=157>>157 samaki
