Vì xe thứ hai chở ít hơn xe thứ nhất 3 bao gạo thì xe thứ hai chở ít hơn xe thứ nhất 150kg gạo, nên 3 bao gạo sẽ nặng 150kg.
1 bao gạo nặng số kg là:
150 : 3 = 50 (kg)
Xe thứ nhất chở số kg gạo là:
50 x 60 = 3000 (kg)
Xe thứ hai chở số kg gạo là:
3000 - 150 = 2850 (kg)
Đáp số: Xe thứ nhất: 3000kg; Xe thứ hai: 2850kg.
