$18.5 \%$ of $220 + 12.4 \%$ of $680 = ?$

$A$ piece of cloth measured with a metre stick,which is $1 \ cm$ short,is found to be $100 \ m$ long. Reckoning the metre stick as being correct,what is the actual length of the cloth in $cm$?

$250 \%$ of $? \div 250 - 444 = 200$

$4767$ exactly divides $xxx\,341$. The missing digits are:

$\left[ {10 + \left\{ {4 \times \left( {\overline {\frac{2}{3} + \frac{1}{4}} \times \sqrt {\frac{{144}}{{121}}} + 23} \right) \div 12 + 5} \right\} - 3} \right] = ?$

In a division sum,the quotient is $120$,the divisor is $456$,and the remainder is $333$. Find the dividend.
