You have made 20% profit. Your balance is now 900 british pounds. What was your pre-profit balance?
- 700 british pounds
- 750 british pounds
- 800 british pounds
Explanation from PART66Online
A 20% profit makes the balance 120% of the original, so balance = original * 1.20. Reversing this, original = 900 / 1.20 = 750 pounds. Checking: 750 plus 20% of 750 (150) equals 900, confirming the answer.
