{961+(961÷ 2)+[(961÷ 2)+135.4]} ÷ 3 = 685.8 (tons)
2、
Cookies (44.2-24.3) ÷ (3-1) =10 (yuan)
Candy 44.2- 10×3= 14.2 (yuan)
3、
Half is1.5-1.05 = 0.45kg.
So honey is 0.45/ 1/2 = 0.9 kg.
Bottle1.5-0.9 = 0.6kg.
4、
12÷4=3 (yuan)
9÷4=2.25 (yuan)
2.25+3=5.25 (Yuan)
5、
69.4/2 = 347,000 Jin
(34.7-1.8)/2 =164500 kg
(34.7+1.8)/2182500 kg
34.7-18.25 =164500 kg
6、
Tonnage of a batch of goods per vehicle:1.5/(13-11) = 0.75.
Tonnage of the first vehicle: 0.75* 13=9.75.
Transport tonnage of the second vehicle: 0.75* 1 1=8.25.
7、
15 kg of flour is more expensive than 15 kg of rice: 0.14×15 = 2.1(Yuan).
Per kilogram of rice: (50.4-2.1) ÷ (20+15) =1.38 (yuan).
Per kilogram of flour:1.38+0.14 =1.52 (Yuan).
8、
The horizontal speed of the road is 20km/h,
The uphill speed is (20-2) ÷1.2 =15 (km/h).
Downhill speed: 15× 1.6 = 24 (km/h).
Take the flat road for one round trip: 40+40 = 80km,
Time: 80÷20 = 4 hours;
Uphill: 45+36 = 8 1 (km)
Time: 8 1÷ 15 = 5.4 (hours);
Downhill: 45+36 = 8 1 (km)
Time: 8124 = 3.375 (hours).
Round trip time: 4+5.4+3.375 = 12.775 (hours) ≈ 12.78 (hours).
9、
Seven days a week,
Four Mondays are 4*7=28 days.
There will be another Monday, neither the first day nor the last day.
So this month * * * has 28+3 =3 1 day.
The second and penultimate day is Monday.
So the first day is Sunday.
10、
Each box can hold: 300(2×2+6)= 30 pairs.
Each wooden case can hold 30×2=60 pairs.
