Since Brian catches 2 / 5 times less fish than Chris per trip, Chris catches 2 / 5 * 400 = 160 more fish in one fishing trip. Chris's total number of fish in one trip is 400 + 160 = 560 fish. In 10 trips, Chris catches 560 * 10 = 5600 fish. If in his two trips Brian catches 800 fish, and he goes fishing twice as often as Chris, if Chris goes fishing 10 times, Brian will catch 800 * 10 = 8000 fish. The total number of fish they'll catch if Chris goes fishing ten times is 8000 + 5600 = 13600. The final answer: 13600. <hau> Idan Brian ya kama kifi 400 a tafiya daya, ya kama 2 * 400 = kifi 800 a tafiye-tafiye biyu.
