Meat problem

Algebra Level 2

You went into a store and came to shop. One of them was on a 10% discount, and the additional tax on that meat was unfortunately 100%. The final price is 10001. When you buy this meat, How much is the original price of the meat? (but we don't think there's a decimal point for all values)

Answer
= 10001 / ( 2 × ( 1 – 10% ) )
= 10001 / ( 2 × 0.9 )
= 10001 / 1.8
= RM 5556.11

Let the original price be 'r'.

Then discounted price = 90 r 100 =\frac{90r}{100}

Final price = 200 × 90 r 100 × 100 = 10001 =\frac{200 \times 90r}{100\times 100} = 10001

Solving the above equation, r ≈ 5556 r≈5556

  • answer = a
  • discount = b

  • FinalPrice = 10001

  • b = (a*2) - (1/10) #b = '1111'

  • a * 2 # 5556(or other) * 2 = 11112 (standard for 5556)
  • a - b # 11112 - 1111 = 10001
  • if a = FinalPrice , # 10001 = 10001
  • print("Yes")
  • else
  • print("nah")
  • So answer is "5556".
