A number is decreased by $30\%$, then increased by $27\%$ and then further increased by $20\%$. What is the net increase/decrease percentage in the number (correct to the nearest integer)?

Two numbers are $30\%$ and $50\%$, respectively, more than a third number. The ratio of the second number to the first number is:

The area of a circle is $38.5{\text{cm}}^2$. Find its circumference (in $\text{cm}$). (Use $\pi =\frac{22}{7}$)

The average of $33$ numbers is $70$. The average of the first $17$ numbers is $65$ and the average of the last $17$ numbers is $74$. If the $17$ th number is excluded, what is the average of the remaining numbers (approximate to one decimal place)?

In $△ABC$, $AB$ and $AC$ are produced to points $D$ and $E$, respectively. If the bisectors of $\angle CBD$ and $\angle BCE$ meet at point $O$, so that $\angle BOC=76^{\circ }$, then find the measure of $\angle A$.
