Question

If x∈ W , then the solution set of the inequation -x > - 3 , is

( a) {1 , 2} (b) {0,1,2} (c) {0,1,2,3 …} (d) { -4, -5, -6…}

Answer 1

Answer:

The correct answer is option (b) .  

Step-by-step explanation:

Given inequality is  $-x>-3$

                              $\Rightarrow 3>x$, take constant to LHS and variable to RHS

                              $\Rightarrow x<3$

Also given x is whole number, so x can be 0,1 or 2

                              $\therefore x\in\{0,1,2\}$
