For the following questions answer them individually
58% of 842 + ? = 1200
$$(59)^{2} + (12)^{2} = (?)^{2} + 600$$
$$2\frac{1}{5}+3\frac{2}{5}-1\frac{1}{3}=?$$
1221 + 1117 = ? % 6680
52% of (?) = 3387.28
$$\sqrt{12321}=?$$
72% of 654 - 41% of 312 =?
$$2376 \div 32= ?$$
67539 + 43908 = ? + 78902
$$? \div 45 \times 9 = 315$$
