There are three switches downstairs. Each corresponds to one of the three light bulbs in the attic. You can turn the switches on and off and leave them in any position.
How would you identify which switch corresponds to which light bulb, if you are only allowed one trip upstairs?

  1. number the switches
  2. switch one of them on, lets say number 1
  3. wait for 5-10 mins, switch the number 1 off and switch the number 2 on and
  4. go upstairs and check the temperature of the bulbs off- cold one is number 3, warm one is number 1, the one which is still on- is number 2

On occasion of Diwali (a Hindu festival), the local ice cream seller is selling ice cream at an 80% discount. But, he got just two flavors, vanilla and cocoa-chipped. He is selling vanilla at Rs 1 and Choco-chip at Rs 2. However, he is giving just one ice cream to each person.
Shruti went to the shop and give the seller Rs.2 and without asking her the seller gives her Choco-chip ice cream. Next, Anmol comes and also gave the seller the same amount i.e. Rs 2. Now the seller asks Anmol which ice-cream does he wants.

Why such a different behavior towards Shruti and Anmol?

Suppose you’re on a game show, and you’re given the choice of three doors: Behind one door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who knows what’s behind the doors, opens another door, say No. 3, which has a goat. He then says to you, “Do you want to pick door No. 2?” Is it to your advantage to switch your choice?
