26 cows eat 3 mu of grass in 3 days, and 17 cows eat 28 mu of the same grass in 84 days. Ask: How many cows can eat 40 mu of the same pasture for 24 days? (The amount of grass in each mu of grassland is equal, and the growth rate of grass is equal) (use arithmetic method to solve)
26头牛吃了3亩草地的草，3天可以吃完，17头牛吃28亩同样草地的草，84天可以吃完，问：同样的牧草40亩可供多少头牛食用24天．(每亩草地原有草量相等，草生长速度相等)(用算数法解)
