Let the first number be n
(10n+n+1)+10(n+1)+n=(n+1+n)10+n+1+n
Solution: 11n + 1 + 10N + 10 + n = 10N + 10 + 10N + 2n + 1
22n+12=22n+12



[x squared by (x + y)] - x + y=

Who can explain the "how to stipulate" in the VAT?


Divided by 1.17 is divided by (1 + 17%). The reason for dividing by 1.17 is that the number before the division sign is the price including tax, while the real income refers to the price excluding tax, so it needs to be converted. Therefore, it has to be divided by 1.17. This is not a rule, but a calculation method



Why divide the tax by 1.17 instead of multiplying by 0.17 and then reduce the sales?
The results of these two calculations are almost the same, but the amount is dozens of yuan less. Why?
But one thing I don't quite understand is: why do I have errors when I separate and combine the formula?


Because the price includes tax, for example, if the price includes tax is 1000 yuan, the calculated tax is 1000 / 1.17 * 0.17 = 145.30
1000 / 1.17 = 854.70 is the price excluding tax
If the price excluding tax is 1000 yuan, the tax is 1000 * 017 = 170 yuan



The quotient of a number multiplied by 34 and divided by 17 is 12?

Component tax price = cost × (1 + cost profit margin) / (1-consumption tax rate) I can't understand why divided by (1-consumption tax rate)?
Why is it divided and then 1-consumption tax rate reduced?


The sales volume of a goods subject to consumption tax should include three parts: the cost of the goods, the profit of the goods, and the consumption tax that the goods should pay (the consumption tax is the tax within the price, which should be included in the sales volume)



5 out of 6 times 17 + 5 out of 6 divided by 1 out of 19, 7 out of 8 divided by 1 out of 34, 7 out of 8 multiplied by 6, it's coming


5 / 6 times 17 + 5 / 6 divided by 1 / 19 = 5 / 6 * (17 + 19) = 30
7 / 8 divided by 1 / 34 + 7 / 8 multiplied by 6 = 7 / 8 * (34 + 6) = 35
