- First, approximate v1763.98 to the nearest whole number. Since 1764 is a perfect square, v1763.98 is approximately 42.

- Next, approximate v1444.04. The perfect square closest to this is 1444, and its square root is 38.

- Calculate 39.99% of 149.92. Approximating, this becomes 40% of 150.

- 40% of 150 is computed as: (40/100) * 150 = 60.

- Now calculate: 42 + 38 - 60.

- This simplifies to: 80 - 60 = 20.

The correct and highlighted answer is:
