The arrow spinner travels 360 degrees for every complete revolution.
In 10 revolutions, the arrow spinner completes 360 x 10 = 3600 degrees.
The remaining 240 degrees is left. Also, note that each of the sectors holds 60 degrees.
240 = 60 x 4. Therefore, the arrow spinner travels exactly 4 sectors from its current position.
That is, the arrow spinner reaches the midway of the sector containing the square.

Solution


Given
In this question, we are given
    • The figure of a circle, divided into 6 sectors of equal area, contains an arrow representing a spinner.
    • The spinner is rotated 3840 degrees in a clockwise direction from the position shown.

To Find
We need to determine
    • Which of the given diagrams indicates the sector to which the arrow on the spinner will point.

Approach & Working
We know that for a complete revolution of 360 degrees, the pointer will return at the starting point.
    • 3840 = 360 * 10 + 240
    • Hence, after completing 10 complete revolutions, the pointer will move for another 240 degrees clockwise.

As the circular region is divided into 6 regions of equal area, each region is equivalent to 60 degrees.
Therefore, to make a movement of 240 degrees, the pointer will shift 4 more regions, and end up showing at the square.

Hence, the correct answer is option B.

I marked D, thinking that we are rotating the disk, not the arrow. These questions are sometimes so hard to read.

'Arrow representing as spinner', I guess I missed this

Each sector of the circle is made up of 360/6 = 60 degrees.

The spinner spins 3,840/360 = 10 240/360 = 10 ⅔ rotations. For the 10 full rotations, the spinner lands where it is shown. For the extra ⅔ rotation, or 240 degrees, the spinner rotates 4 more sectors clockwise; thus, it will land on the sector containing the square.

Answer: B

I also got D. The spinner is clockwise, not the arrow.

I choose D as the spinner rotates clockwise for 240 degrees. Please help explain where I got this wrong.

3600 can be neglected out of 3840 because that will bring the arrow back to it's original place.

So we need to worry about remaining 240 degrees.

Since 6 sectors of 60 degree each, we need to shift 4 sectors. And that means it will point to square shape

All those going for D are going wrong in understanding what is spinning.
3600 gone and the figure and spinner will be as it is shown.
Now remaining 240.
If you rotate the spinner, that is the arrow, as it is given , the arrow will move 4 steps clockwise and would stop on squareand B will be correct.
However if you rotate the figure or the board , the trapezium or D will be the answer.

But here the spinner is given as arrow so B
