If P = 2, Q = 4, R = 11, S = 21, and T = 25, then, what is $\left( R\text{ }\times \text{ }R\text{ }-\text{ }S \right)\text{ }\div \text{ }T\text{ }=?$ A)  R                     B)  Q        C)  P        D)       S

$(R\times R-S)\div T=(11\times 11-21)+25$                 $=(121-21)\div 25$                 $=100\div 25=4\to \mathbf{Q}$
