Mr. Inahurry sold his house for $27,000, which is a 10% loss over what he originally paid for it. What did he pay for the house originally?

Answer: $30,000

Step-by-step explanation:

If Mr. Inahurry had a 10% loss, it means that he paid X for the house and only got back 90% (100% - 10%) of what he paid.

This way X. 90% = 27,000

X. 0.90 = 27,000

X = 27,000/0.9

X = 30,000

Counter-proof: 30,000. 10% = 30,000. 0.10 = 3,000

30,000 - 3,000 = 27,000
