Ngày thứ ba bán được:
\(2000-800-800\cdot\dfrac{4}{5}=560\left(kg\right)\)
ĐỔI 2 tấn = 2000 kg
Ngày thứ 2 cửa hàng bán được số ki lô gam đường là
400 * 3/5 = 240 <kg>
Cửa hàng đã bán được số ki lô gam đường là
2000 - <400+240> = 1360 <kg>
2 tấn = 2000 kg
Số kg đường ngày thứ hai cửa hàng bán được là :
400 x 3/5 = 240 ( kg)
Số kg ngày thứ nhất và ngày thứ hai cửa hàng bán được là :
400 + 240 = 640 ( kg)
Số kg đường còn lại sau khi bán trong hai ngày là :
2000 - 640 = 1360 ( kg)
Đs : 1360 kg đường
Ngày thứ 2 bán được số kg gạo là :
400 : 5 x 3 = 240 ( kg )
Đổi : 2 tấn = 2000 kg
=> Tổng ngày đầu và ngày 2 bán được số kg gạo là :
400 + 240 = 640 ( kg )
=> Số đường còn lại là :
2000 - 640 = 1360 ( kg )
Đ/S : 1360 kg
Đổi 1,5 tấn = 1500kg
Ngày thứ 2 cửa hàng bán được: 350x2 = 700(kg)
Ngày thứ 3 cửa hàng bán được: 1500-700-350=450(kg)
Đổi 2 tấn = 2000 kg
Ngày thứ hai bán được số kg đường là
\(800\cdot\frac{4}{5}=640\)( kg)
Ngày thứ 3 bán được số kg đường là
\(2000-800-640=560\)( kg)
2 tấn = 2000 kg
ngày thứ 2 bán được :
800 x 4/5 = 640 (kg)
ngày thứ 3 bán được :
2000 - 800 - 640 = 560 (kg)
giải
số đường ngày thứ 2 bán đc là:
300 x 2 = 600 (kg)
số đường ngày thứ 1 và ngày thứ 2 bán đc là:
300+600= 900 (kg)
Ngày thứ ba bán đc bn tấn đường là:
1 tấn = 1000kg
1000-900= 100 (kg)
đáp số : ngày 2 = 300(kg)
ngày 3 = 100(kg)
1 tấn = 1000 kg
ngày thứ ba bán được số kg đường là
1000 - 300 - ( 300 x 2 ) = 100 ( kg )
