Party A and Party B are playing the game of stone scissors cloth on the climbing stones. Each time, they have to decide the winner. The winner goes up five steps, and the loser goes down three steps The game starts on the 50th step. After playing 25 times, a is 40 steps higher than B. at this time, which step are a and B on?

Party A and Party B are playing the game of stone scissors cloth on the climbing stones. Each time, they have to decide the winner.

Each time after winning or losing, the height difference between the two increased by 8. The height difference between a and B increased by 40 steps, which is equivalent to a net win of 5 times. The remaining 20 times must win 10 times, that is, each person went up 5 * 10 = 50 steps, and then down 3 * 10 = 30 steps. That is equivalent to 20 times after winning or losing, they both stood on the 70th step. In the next five times, a won all, went up 5 * 5 = 25 steps, stood on the 95th step, B lost all, and went down 3 * 5 = 15 steps, Standing on the 55th step
The above answers are only personal opinions, for reference only



A and B two people play stone scissors and asked two people to play this game, the first game will be able to tell the probability of winning or losing


On the other hand, what is the probability of a draw in the first game
The probability of all scissors is 1 / 9 (1 / 3 times 1 / 3), the probability of all hammers is the same, so is the cloth
So the probability of a tie is 1 / 3 (1 / 9 * 3),
So the opposite is to divide the winner and loser is 1 minus 1 / 3 to 2 / 3



Xiaoming's house is on the sixth floor. He and his father started to play the game of "stone, scissors and cloth" from the fourth floor. It is stipulated that every time the winner can go up three steps, and the loser has to go down one step. After playing 20 times, father and Xiaoming both go from the fourth floor to the sixth floor. How many steps are there between the two floors?


There are 20 steps between the two floors



Xiaoming and his father wait for steps. There are 60 steps in total. Dad steps up three steps and Xiaoming steps up two steps. How many steps have Xiaoming and his father never climbed?


Grade 20
Because:
60 / 3 = 20, so there are 20 multiples of 3 in 60, that is, dad has climbed 20 steps;
60 / 2 = 30, so there are 30 multiples of 2 in 60, that is, Xiao Ming has climbed 30 steps;
The least common multiple of 2 and 3 is 6, and 60 / 6 = 10, so there are 10 multiples of 6 in 60, that is, both dad and Xiao Ming have been registered at level 10
Therefore, the number of steps that neither dad nor Xiao Ming has climbed is 60 - (20 + 30-10) = 20



Xiao Ming and his father compete to climb stairs. They live on the third floor, with a total of 40 steps. Dad steps up three steps, Xiao Ming steps up five. From the door, how many steps have Xiao Ming and his father climbed?


The common multiple of 3 and 5 is 15.30?



Xiao Ming and his father are on the stage. There are 60 steps in total. Dad steps up three steps and Xiao Ming steps up two. How many steps are there that Xiao Ming and his father haven't climbed?


There are 60 / 2 = 30 divided by 2, 60 / 3 = 20 divided by 3, 60 / 6 = 10 divided by 2 and 3, so the number of steps that both of them have stepped on is 30 + 20-10 = 40, and the number of steps that neither of them has stepped on is 60-40 = 20. A: there are 20 steps that neither Xiao Ming nor dad has stepped on



Xiaoming and Xiaohua play stone, scissors and cloth games. They play them once. What percentage of Xiaoming will win?


Xiaoming out of stone, Xiaohua may out of scissors and cloth, scissors, Xiaoming win, otherwise lose, out of the same draw
Xiao Ming gives scissors, Xiao Hua Stone and cloth, gives stone to win, lose and draw
Xiaoming out cloth, Xiaohua stone scissors out scissors win lose, out of the same draw
In any of the three cases, the probability of Xiaoming winning is 1 / 3



1. How to calculate 3, 9 and 10 to be equal to 24


(1 10) x3-9 = 24



Three nines and one one. How to calculate equal to 24


There is no solution in the case of four operations
You can do it by adding a root
√9 ×9-√9 ÷1=24



How can three ones and a nine be equal to 24?
How can 1,1,1,9 be equal to 24?


[(9-1)/(1+1)]!
=[8/2]!
=4!
=24
Factorial of 4 = 1 * 2 * 3 * 4 = 24
