Hey Bunuel

Can we assume that the figure given is drawn to scale ? Most of the resources I go through suggest that it's always better not to rely on the figure. I approached the question in the same but wasn't sure about the accuracy of figure.

No need for accuracy in fig...
fig just shows that beam lies in first quadrant...
And as shown 3690=360*10+90..
then beam lies ahead of 90 deg. moving clockwise direction
being its initial position is 1 deg. or 89 deg it would lie in 4th quad ..
As 1+90=91 deg...4th quad
or 89+90=179=4th quad..

The figure above shows the present position on a radar screen of a sweeping beam that is rotating at a constant rate in a clockwise direction. In which of the four quadrants will the beam lie 30 seconds from now ?

(1) In each 30-second period, the beam sweeps through 3690°
(2) r = 40



Now beam is at first quadrant
In 30 seconds -> 3690 degrees rotation => after 30 seconds radar beam will be at first quadrant + 90 degrees clockwise => fourth quadrant.

A or D can be answer


but considering 2nd statement => r=40 is insufficient => A is the answer....


A
