Question

Red, Yellow, Blue, White and Green colours bulbs joined one by one consecutively to a wire for decoration purpose, then which colour of bulb will be there on 87th place to that wire ?​

Answer 1

ANSWER::

Yellow

EXPLANATION::

There are 5 bulbs all total. If we put them consecutively then every 5th bulb will be of green and again the sequence continues with red then yellow then blue and many more.

So, we know that 85 is a multiple of 5, so 85th position of bulb is occupied by green coloured one. Then 86th bulb would be red and 87th of yellow.

TRICK::

To solve questions like this first we have to find out the number of items and if asked about the special position see for the nearest multiple(but smaller than required number) of the number of items like if asked for 87th bulb then nearest multiple of 5 is 85 so then just remember the sequence and substitute it for every position to get the answer.
