HOW MANY
IDENTIFIED IT? - Answer
Age group: 6 - 12 years old
Here is the answer to the question I had asked in my previous post!
The question was:
" In an innovative contest, four kinds of fruits - apple, bananas, oranges and plums are placed in four different boxes. The boxes are closed and not transparent. Participants are asked to guess correctly the contents of each box. In all, 123 participants participated. 43 of them could not identify any of the boxes correctly. 39 of them could guess one box correctly. However, as many as 31 could guess two correctly but were wrong in identifying the other two.
Can you tell how many people identified only three boxes correctly and how many identified all four? "

Now coming to the Answer!
It is actually quite simple, all the information you need is right there in the question. Just pause and think...
Is it possible to identify ONLY three boxes correctly?
NO! If you identify three boxes correctly, you will be sure to identify the fourth box correctly as well, since that is the only box remaining.
So, the remaining participants according to the question were:
123 - (43+39+31) = 10 people
Hence, all 10 remaining people guessed all four boxes correctly, and none identified ONLY three boxes.
Therefore, the final answer is:
Number of people who identified only 3 boxes correctly -> none
Number of people who identified all 4 boxes correctly -> 10 people
