Question 1. You’re In A Room With Three Light Switches, Each Of Which Controls One Of The Three Light Bulbs In The Next Room. Find Out Which Switch Controls Which Bulb. All Lights Are Initially Off, And You Cannot See Into One Room From The Other. You Can Check The Room Only Once. How Can You Determine Which Switch Is Connected To Which Light Bulb?
Call the switches 1, 2, and 3. Leave Switch 1 off. Turn Switch 2 on for five minutes and then turn it off. Turn Switch 3 on and leave it on. Enter the room. The bulb that is on is controlled by Switch 3 (the one you left on). Feel the light bulbs that are off for heat. The bulb that is off and warm is controlled by Switch 2 (the one you turned on, then off). The bulb that is off and cold is controlled by Switch 1 (the one that you didn't turn on).
Instead of describing what it looks like, try to identify what it does and how it can assist operations in the company by just going through and talking about its functionality, e.g., "this can be used to store contact details, make phone calls, send emails, take photos or videos, etc." You could also relate it to the job or the workplace and talk about how the mobile phone would be used.

Question 8. You Wake Up Early One Morning And Find The Light In Your Bedroom Is Broke. You Get Dressed In The Dark. Your Drawer Has Socks Of Three Different Colors: Red, Yellow, And Blue. How Many Socks Do You Have To Take Out To Be Certain Of Having A Matching Pair?
Let’s start drawing socks. There will be three scenarios −
If the first sock is red. If the second is red, you have a matching pair. But what if it is isn’t red?
If the second sock is yellow. If the third is either yellow or red, then you have a pair. If it is blue, then you draw again.
If the third sock is blue. Now you have one of each. Since your next sock must be either red, yellow, or blue, you are bound to have a pair.
Once you have four socks, you are guaranteed to have a pair

Question 10. You Are Blindfolded And Sit In Front Of A Table. On The Table Are Many Coins, 10 Of Which Have Heads Facing Up. How Do You Split The Group Of Coins Into Two Groups Such That The Same Number Of Coins Are Heads-up In Each Group?
You don’t know how many coins there are and you can’t tell which side is facing up in any way.
Let’s say there are 50 coins and we separate 10 of them. Now we have a group of 10 and a group of 40.
Let’s assume there are 3 heads in the group of 10. Then there will be 7 heads in the group of 40.
Now we turn over all the coins in the group of 10.
That’s it! 7 heads in each group!
