Question

There are 300 light bulbs lined up in a row in a long

room. Each bulb has its own switch and is currently

switched off. Each bulb is numbered consecutively from

1 to 270. You first flip every switch. You then flip the

switch on every second bulb(turning off 2, 4,6. ). You

then flip the switch on every third bulb (3, 6,. ). This

continues until you have gone through the process 300

times.

And how many of the light bulbs are illuminated now?

Answer 1

Flipping the bulbs is an illustration of sequence and patterns

17 bulbs would remain on.

How to determine the number of bulbs that will be on?

The sequence of turning the bulbs off and on, would change the state of the bulbs until the 300th process.

While changing the state of the bulbs, the bulb at the perfect square positions would remain on.

There are 17 perfect square numbers between 1 and 300 (inclusive)

Hence, 17 bulbs would remain on.
