CThe number of graduates who are also coffee lovers but not soldiers is 65

D.The number of coffee lovers who are both graduates and soldiers is 90.

Answer:

C. The number of graduates who are also coffee lovers but not soldiers is 65

Read Explanation:

The number of graduates who are also coffee lovers but not soldiers is 65.

  • Graduates who are also coffee lovers but NOT soldiers: Look at the overlap between the Coffee lovers and Graduates circles that excludes the Soldiers circle. This region is explicitly 65 (This is the correct statement).

  • Soldiers who are neither coffee lovers nor graduates: Look at the standalone region for Soldiers only. This number is 141 (not 193).

  • Coffee lovers who are both graduates and soldiers: Look at the center region where all three circles intersect. This number is 52 (not 90).

  • Soldiers who are also coffee lovers: Sum both intersection areas between Soldiers and Coffee lovers (90+52=14290 + 52 = \mathbf{142}).
