The price of Haier computer has been reduced by 2 / 11, which is 1000 yuan lower. How much is the price now
4500 or 5500?
The answer is 5500 yuan is the original price, now the price is 4500 yuan
The calculation is as follows:
Let the original price be x, then 2x / 11 = 1000
Therefore, the original price x = 5500
Verification: now the price is 9x / 11 = 9 * 5500 / 11 = 4500
The difference between the original price and the present price is exactly 1000 yuan
Verify that the answer is correct
A washing machine now costs 1260 yuan, 10% lower than the original price. How much is the original price of each washing machine?
Use equation solution! Online and so on, thank you
I've forgotten what an equation is
I don't know, right
Suppose the original price is X
10% lower than the original price, that is, the current price is 90% of the original price
Then x * (1-10%) = 1260
We can get x = 1400
