Solve: \(80\%\) of ? = \(\sqrt{250 \times 44 + 40 \times 8500 \div 100}\). Find ?.

1. 120
2. 130
3. 140
4. 150

Correct answer: 150

Solution

Inside the square root, \(250\times 44 = 11000\) and \(40\times 8500\div 100 = 3400\), so the sum is 14400. Its square root is 120. Since 80% of the number is 120, the number is \(120/0.8 = 150\).
