A suit now costs 1400 yuan, 30% lower than the original price. How much is the original price?
1400 divided by (1-30%) = 2000 yuan, right
The price of a washing machine is 640 yuan, which is 19% lower than the original price. How much is the original price?
It was 760 yuan
Take my answer
The price of a washing machine is 640 yuan, which is 20% lower than the original price. How much is the original price? How much discount does this washing machine sell in the market
So the original price is 640 / (1-20%) = 800 yuan. The discount is 640 / 800 = 8 / 10! That's a 20% discount!
