Correct Answer: 97.2°
Solution : The measure of the central angle is equal to $\frac{\text{Percent share of the corresponding sector}}{100}\times360$. Measure of central angle for Q = $\frac{15}{100}\times360$ = 54$^\circ$ Measure of central angle for U = $\frac{12}{100}\times360$ = 43.2$^\circ$ $\therefore$ The sum of the measures of the central angles of the sectors corresponding to the number of girls in colleges Q and U, taken together is = 54$^\circ$ + 43.2$^\circ$ = 97.2$^\circ$ Hence, the correct answer is 97.2$^\circ$.
