đổi 40 tấn = 40000kg
vì số bao gạo tẻ bằng số bao gạo nếp nên gọi số bao gạo mỗi loại là x (bao)
số kg gạo tẻ là: 50x (kg)
số kg gạo nếp là: 30x (kg)
vì có tổng là 40 tấn gạo và tẻ nên ta có: 50x + 30x = 40000 => x= 500 (bao)
số gạo tẻ: 50 x 500 = 25000 kg = 25 tấn
số gạo nếp: 30 x 500 = 15000 kg = 15 tấn

Gọi số bao gạo mỗi loại là a
Số gạo tẻ là 50xa
Số gạo nếp là 30xa
Đổi 40 tấn = 40.000 kg
50xa + 30xa = 40.000
80a = 40.000
a = 500
Số gạo tẻ là: 50 xa = 50 x500 = 25.000 kg = 25 tấn
Số gạo nếp là 30xa = 30 x 500 = 15.000 kg = 15 tấn

135 tấn = 135000 kg
số bao là
135000 :(50+40)= 1500 ( bao)
mỗi kho có số bao là
1500:2= 750(bao)
kho 1 có 750 x 50= 37500(kg)
kho 2 có 750 x 40= 30000(kg)
đổi 37500 kg =75/2 tấn
30000kg = 30 tấn
đáp số...

140 bao gạo tẻ nặng số ki - lô - gam là :
10 x 140 = 1400 ( kg )
120 bao gạo nếp nặng số ki - lô - gam là:
5 x 120 = 600 ( kg )
Có tất cả số tấn gạo là :
1400 + 600 = 2000 ( kg )
Đổi 2000 kg = 2 tấn
Đáp số: 2 tấn gạo
Số kg gạo tẻ là:
50 x 32 = 1600 (kg)
Số kg gạo nếp là:
59 x 45 = 2655 (kg)
Vậy có tổng cộng:
1600 + 2655 = 4255(kg) = 4,255 tấn
ĐS: 4,255 tấn
