What will come in place of the question mark (?) in the following questions ?
$$8\frac{1}{4} + 60\% of \frac{6}{5} = 15 - ?$$
7275.84 - 889.4 + 124.518 = ?
$$\frac{12^2-4^2}{9^2-3^2}=?$$
18800 $$\div$$ Â 470 $$\div$$ Â 20 = ?
$$\sqrt{?}+136=\frac{5}{8}$$ of 320
777.07 + 77.77 + 0.77 + 7.07 + 7 +77 = ?
0.04 $$\times$$ ? = 0.000016
35% of 160 + ?% of 180 = 50% of 310
$$4^{7} \div 16^{4} \times \sqrt{16}=?$$
0.99 $$\times$$ 14 + 11 $$\div$$ 0.7 = ?
