$\frac{? \div 12}{0.2 \times 3.6} = 2$

$337.62 + 8.591 + 34.4 = ?$

$\left(\frac{24}{9}\right)^{2} \times \frac{399}{39} \div \frac{41}{899} = ?$

If $2994 \div 14.5 = 172$,then $29.94 \div 1.45 = ?$

$A$ sum of $Rs. 1360$ has been divided among $A, B$ and $C$ such that $A$ gets $\frac{2}{3}$ of what $B$ gets and $B$ gets $\frac{1}{4}$ of what $C$ gets. $B$'s share is (in $Rs.$)

$(1.06+0.04)^{2}-?=4 \times 1.06 \times 0.04$
