The 2000 yuan medical examination package was sold in 300 yuan, which was a good deal. Because the physical examination items of 2000 yuan usually include lung examination, blood pressure examination, rectal examination, prostate examination, body fat examination, eye examination, blood examination and so on. And the cost of each check-up is very high, much higher than that in 300 yuan, so it's a good deal to sell a 2000 yuan medical check-up package to 300 yuan.
