The chart also shows the percentage of respondents who chose exactly two of the methods, exactly three of the methods, and all four of the methods.

­Yes jack5397, it is a question with four overlapping set.

Dropdown 2 gives all the four cases, so we have to focus on the Dropdown 1.

The various options are 
<25%: As all four overlap is 31.9%, so surely all of them are above that...Discard
25-50% and 50% are the other possible cases. But can we say that any of visual, aural, print, and kinesthetic would surely fall in any of the two ranges. So, let us check.

visual: 31.9% + 3.1% + possibly some or most part of (14.9%(exactly two) +  12.1%(exactly three)). Thus 35% + x, where x could be 0 to 27%. Range = 35% to 35+27 or 62%. Hence, could fall in any of the two ranges 25-50 or >50.

aural: 31.9% + 7.1% + possibly some or most part of (14.9%(exactly two) +  12.1%(exactly three)). Thus 39% + x, where x could be 0 to 27%. Range = 39% to 39+27 or 66%. Hence, could fall in any of the two ranges 25-50 or >50.

print: 31.9% + 19.1% + possibly some or most part of (14.9%(exactly two) +  12.1%(exactly three)). Thus 51% + x, where x could be 0 to 27%. Range = 51% to 51+27 or 78%. Hence, would surely fall in the range >50...Answer

kinesthetic: 31.9% + 11.8% + possibly some or most part of (14.9%(exactly two) +  12.1%(exactly three)). Thus 43.7% + x, where x could be 0 to 27%. Range = 43.7% to 43.7+27 or 70.7%. Hence, could fall in any of the two ranges 25-50 or >50.

Solution: Greater than 50% and Print

Hi! As we know only one and all four, we can conclude that Printing has more than 50 percent. It might have some part of only two and only three as well but more than 50 we are already sure of.

chetan2u I'm unable to understand the calculations here:

visual: 31.9% + 3.1% + possibly some or most part of (14.9%(exactly two) + 12.1%(exactly three)). Thus 35% + x, where x could be 0 to 27%. Range = 35% to 35+27 or 62%. Hence, could fall in any of the two ranges 25-50 or >50.

Can you please explain why did we start with adding adding 31.9% at the first?

We can see that 19.1% of total employees chose the print method.(We are sure about this through the diagram.)
Moreover, we can see that 31.9% of total employees chose the print method. (Visible through the diagram.). This means that 31.9% of total employees said yes to all 4 method i.e, print/visual/aural and kinesthetic.
Hence, 51% of total employees said yes to Print method. This must be the case. Hence, the correct answer is more than 50% in first blank and print in the second.

P.S: This is must be true question. We are sure about the above mentioned data points with utmost certainty.

the answer is :

31.9% (Total employess) ---> All 4
19.1% (Total employess) ---> print
therefore ---> 31.9+19.1 = 51%(Total employess) must be in the print

Why did you add all four to the other choices? If all 4 were selected that automatically includes the other choices, The question does not specifically say that the respondents chose only one of the choices.

Because by selecting all 4 they inherently select each one. You can therefore add 31.9% to each.

I was initially confused by the solutions explained earlier, wondering why aren't we considering exactly two or exactly three. For those who are still confused even after going through earlier discussions, here is an explanation:
In the tutorials posted by experts earlier, for questions that involve 'must', we have to take the worst-case scenarios => Minimum number possible. It is possible that in exactly two or exactly three scenarios, Print might still not be considered. Eg: Exactly Two - (Visual + Aural), (Kinestetic + Aural), etc. Exactly three - (Visual + Aural + Kinestetic) . Since these scenarios can also come up apart from the ones explained in the very first solution, we have to consider worst case where Print is surely included. Those cases are: (Print only) + (Exactly four). It is a bare minimum condition that should hold true (required to get the answer).

Print = 19.1% + 31.9%

What the chart shows
  • Four training methods: visual, aural, print, kinesthetic
  • Slices for "only visual/aural/print/kinesthetic” and for “exactly two,” “exactly three,” and “all four”
  • Key slice values: visual only 3.1%, aural only 7.1%, kinesthetic only 11.8%, print only 19.1%, exactly two 14.9%, exactly three 12.1%, all four 31.9%
  • Must‐be‐true logic
  • For any method, at least the people who chose “only that method” plus the people who chose “all four” definitely chose it


  • Minimum guaranteed for each method:
      Visual: 3.1% + 31.9% = 35.0%Aural: 7.1% + 31.9% = 39.0%Kinesthetic: 11.8% + 31.9% = 43.7%Print: 19.1% + 31.9% = 51.0%

  • Only print is guaranteed to be above 50%.

  • So the correct fill-ins are “more than 50 percent” and “print"

All four must be added because everyone in that slice chose every method, so they definitely count toward each method’s total. The chart explicitly separates “only X” from “exactly two,” “exactly three,” and “all four,” so totals for a method include several slices, not just the “only” slice
