If a transport team carries a batch of goods, seven twentieth of them will be transported on the first day, and the remaining five eighths will be transported on the second day. If the next day carries 18 tons more than the first day How many tons are there in this shipment

If a transport team carries a batch of goods, seven twentieth of them will be transported on the first day, and the remaining five eighths will be transported on the second day. If the next day carries 18 tons more than the first day How many tons are there in this shipment

The second day = (1-7 / 20) × 5 / 8 = 13 / 32
Total = 18 (13 / 32-7 / 20) = 320 tons

There is a batch of goods in the warehouse. The weight ratio of the goods transported away and the remaining goods is 2:7. If 64 tons are transported away, the remaining goods are only three fifths of the original goods in the warehouse. How many tons are the original goods?
Two methods~

The first method is as follows:
The weight ratio of the transported goods to the remaining goods is 2:7, the weight ratio of the transported goods to the total goods is 2: (2 + 7) = 2:9, the proportion of the remaining part to the total is 1-2 / 9 = 7 / 9, and the remaining 64 tons are transported, so the remaining goods are only three fifths of the original goods in the warehouse. Therefore, the proportion of 64 tons to the total goods is 7 / 9-3 / 5 = 8 / 45, so the weight of all goods = 64 / (8 / 45) = 360 tons
The second approach:
If the total weight of the goods is x tons, there are:
X-X*2/(2+7)-64=X*3/5
The solution is: x = 360
Therefore, the total weight of the goods is 360 tons

There is a batch of goods in the warehouse. The weight ratio of the goods transported away to the remaining goods is 2:7. If another 64 tons are transported away, the remaining goods are only the original goods in the warehouse
How many tons of the original goods in the warehouse?

2÷（2+7）=2/9
There was 64 △ 2 / 9-1 / 9 = 64 △ 1 / 9 = 576 tons

Number reasoning 5 24 6 20 () 15 10 () the answer is 8 and 12 why thank you

5×24=6×20=（）×15=10×（）
So the answer is 8 12
May I help you. I wish you happiness

Numerical reasoning (5,24,6,20,), 15,10,)

5,24,6,20,(8),15,10,(12)
Item 1 * item 2 = 120, item 3 times item 4 = 120,
Multiplication of two equals 120

Numerical reasoning: - 3 / 5, - 2 / 5,1 / 15,7 / 20,16 / 25,
Digital reasoning:
-3/5,-2/5,1/15,7/20,16/25,

38/30
Look at the denominator first. It's obviously a multiple of 5! So the denominator of the number is 30
Let's look at the molecules, - 2 = - 3 + 1,1 = - 2 + 3,7 = 1 + 6,16 = 7 + 9
You can see that the number added is a multiple of 3,
So the molecule is 16 + 12 = 28
So the number is 38 / 30

1 / 3,1 / 2,7 / 10,19 / 20, (77 / 60) number reasoning

The difference between the latter and the former is 1 / 6,1 / 5.1/4,1 / 3,1 / 2 respectively

What is the number of question marks
21, I see
The remaining one is 27, but the answer is 13
Maybe the title is wrong. I'm not sure.

a(n)=a(n-2)*(a(n-1)+1)
a(1)=1
a(2)=1
a(3)=1*(1+1)=2
a(4)=1*(2+1)=3
a(5)=2*(3+1)=8
a(6)=3*(8+1)=27
If the answer is 13, there is always a 2 silly topic written wrong, missing a 5
