Questions: 360 is increased by 25%. The result is then decreased by 50%. What is the final number?

Solution Steps

To solve this problem, we need to follow these steps:

1. Increase 360 by 25%.
2. Decrease the result by 50%.

To increase 360 by 25%, we calculate: \[ \text{Increased Number} = 360 \times \left(1 + \frac{25}{100}\right) = 360 \times 1.25 = 450 \]

Next, we decrease the result by 50%: \[ \text{Final Number} = 450 \times \left(1 - \frac{50}{100}\right) = 450 \times 0.50 = 225 \]
