Six bags of rice were delivered from the canteen, each bag is 50kg. After eating for four days, there are still 116kg left. How many kg do you eat per day on average

Let's eat x kilos a day
4X+116=6×50
4X=300-116=184
X=46
A: an average of 46 kg per day

Eight bags of rice were delivered from cuixiao canteen. Each bag weighs 50 kg. After eating for six days, there are 154 kg left. How many kg do you eat on average every day

Let's eat x kg per day, 6x + 154 = 50 * 8, x = 41

Use the equation to solve 1500 kg of rice transported by the school, eat 84 kg every day, and after a few days, there are 240 kg left?

After X days, there are 240 kg left
X*84+240=1500
84X=1260
X=15
After 15 days, there are 240 kg left
