SSC CGL Tier II level Question Set 6, Geometry 3

SSC CGL Tier II Geometry Questions Set 6 with answers

Solve 10 SSC CGL geometry questions set 6 for tier II in 12 minutes and verify results from answers given. Know how to solve easy from linked solutions.

The ten SSC CGL Tier II level questions in this set are specially selected for variety and depth with no two questions of same type.

The geometry questions are on,

• area of a triangle,
• laws of sines,
• similar triangles,
• trapezium,
• cyclic quadrilateral,
• circles and more.

For best results,

1. this set should be used as a mini-mock test and
2. after timed completion and self-scoring from answers,
3. the difficulties faced should be cleared up from the corresponding solution set.

Link of the detailed solutions is at the end.

Now set the timer and take the test.

By the way don't bother much if you can't solve the questions in 15 minutes of scheduled time. That's an ideal. But with intelligent preparation and practice, you can surely reach this level of competence or better.
