Question 12

Post by TECHNOTHLON on Thu Jul 21, 2016 10:48 am

Question 12 :
Further ahead in the market, Mario finds a huge bag containing 171 mushrooms. He reads the label - “Weighing from 1 to 171 kgs, all varieties within”. Mario is puzzled as he does not know which mushrooms weighs what. He goes to a stone seller who had an offer of “Buy 1, Get 2 Identical Stones Free”. Mario asks him for the different kinds of stones and tells that he can use these to measure any of the mushroom accurately(using common balance). How many different kinds of stones does he buy? (Minimum )

But it is a common balance and hence you can add weights on both sides and types will be 1,7,49 and answer 3

But he don`t know which mushroom is weighting what.But your point is right he will first judge a 1 kg mushroom then 2 3 and so on but i this 3 is appropriate.

25 is like keep 49 at other half and 24 ( all 1s and 7s)
26 is liek remove one 1
Same till 28
Then in 29
Add one on 49 and 3 on oppsite side to get 50-21=29
Like this continue on and on
