20 bao gạo tẻ nặng : 20 x 50 = 1000(kg)
40 bao gạo nếp nặng : 25 x 40 = 1000(kg)
Xe đó chở tất cả số kg gạo là : 1000 + 1000 = 2000(kg)
Đổi : 2000 kg = 2 tấn
Xe đó chở \(50\times20+25\times40=2000\left(kg\right)=2\left(tấn\right)\)

Hướng dẫn giải:
Số gạo tẻ xe chở được là :
25 x 50 = 1250 (kg)
Số gạo nếp xe chở được là :
30 x 25 = 750 (kg)
Tổng số gạo xe chở được là :
1250 + 750 = 2000 (kg)
Đổi 2000kg = 2 tấn
Đáp số : 2 tấn.

Khối lượng của 30 bao gạo tẻ là:
30 x 40 = 1200 ( kg )
Khối lượng của 40 bao gạo nếp là:
40 x 20 = 800 ( kg )
Đổi : 1200 kg = 1,2 tấn
800 kg = 0,8 tấn
Xe đó chở được số tấn gạo là:
1,2 + 0,8 = 2 ( tấn )
Đáp số : 2 tấn gạo
