SSC CGL Tier II level Question Set 1, Algebra 1

1st SSC CGL Tier II level Question Set, 1st on Algebra

SSC CGL Tier 2 question set 1 algebra1

This is the 1st question set of 10 practice problem exercise for SSC CGL Tier II exam and also the 1st on topic Algebra.

For maximum gains, the test should be taken first, that is obvious. But more importantly, to absorb the concepts, techniques and deductive reasoning elaborated through these solutions, one must solve many problems in a systematic manner using this conceptual analytical approach.

Learning by doing is the best learning. There is no other alternative towards achieving excellence.
