Question

Q14) A doctor gave you 6 pills and said that one out of these 6 pills is defective. He was not sure which one is defective but
according to him the weight of the defective pill is not the same as that of the right pills (it might be more or less). To help
you, he gave a weighing machine and said that this weighing machine can be used unlimited times. What is the minimum
number of times the weighing machine must be used for you to find and take 2 right pills?

Answer 1

Answer:

Since there are 6 pills altogether and we exactly don't know which one is the defective pill so we should try 6 times only. We might get the correct 2 pills after weighing 2 times only but we can even get after weighing 4 times also.

So the answer might not be absolutely correct .But in my opinion the answer should be 4.
