#GREpracticequestion In the figure, P and Q are centers .jpg [ 28.93 KiB | Viewed 8011 times ]
In the figure, P and Q are centers of the two circles of radii 3 and 4, respectively. A and B are the points at which a common tangent touches each circle.
Quantity A |
Quantity B |
\(AB\) |
\(PQ\) |
Quantity A is greater.
Quantity B is greater.
The two quantities are equal.
The relationship cannot be determined from the information given.

\(ABPD\) is a rectangle and \(AB=DP\). A is \(\angle90°\) so also the corresponding angle D must be \(90°\). If D is \(90° PQ\) is the longest side of the \(\trinagle PDQ\).
Sp \(PQ\) is > of side \(DP\). \(DP\) is \(= AB\).
Therefore, \(PQ > AB\)
B is the answer
