# $$\Large 1178.999 \times 25.0001 - \sqrt{?} \times 16.0011 = 29075$$

 A) 25 B) 15 C) 575 D) 625

 D) 625

$$\Large 1178.999 \times 25.0001 - \sqrt{?} \times 16.0011 = 29075$$

$$\Large 1179 \times 25 - \sqrt{?} \times 16 = 29075$$

$$\Large 29475 - \sqrt{?} \times 16 = 29075$$

$$\Large \sqrt{?} \times 16 = 29475 - 29075 = 400$$

$$\Large \sqrt{?} = 25 => ? = 25 \times 25 = 625$$
