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
