### Instruction:
 Samaki 1,800 wanakwenda upande wa magharibi, 3,200 wanakwenda upande wa mashariki, na 500 wanakwenda kaskazini. Ni idadi gani ya samaki waliobaki baharini, ikiwa wavuvi wanakamata 2/5 ya samaki waliokwenda upande wa mashariki na 3/4 ya samaki waliokwenda upande wa magharibi?


### Response:
 Idadi jumla ya samaki ni 1800+3200+500=<<1800+3200+500=6000>>6000.
Idadi ya samaki waliokamatwa ni .8*1800+.6*3200=<<.8*1800+.6*3200=2720>>2720.
Idadi ya samaki waliobaki baharini ni 6000-2720=<<6000-2720=3280>>3280.
