**For the first time SSC 2016 examination will be held in Computer Based pattern and managing time will be one of the important factor while solving the questions. So in order to make students familiar with such a situations we are providing questions in a time based manner , which will help students to manage the time properly.**

**1. If a+b+1=0 then what is the value of(a ^{3}+b^{3}+1-3ab) ?**

Solution:

∵a+b+c=0⇒a

here c=1.

^{3}+b^{3}+c^{3}-3abc=0,here c=1.
