plot the graph of sin(x) and x/2.
From just observing it we can see that it intersects at 3 points and hence the answer is 3.

they give sin(x)=x/2    0 is the one solution because sin(0)=0  so one solution exist for this question if you take pi/2  or pi/4 you have to p[rove that sin pi/2=pi/4  or sin pi/8=pi/16  which is greater than one
