If you feel like there are things I can do to make it better, let me know.

Fair Warning: I am doing this right now with the intent on following through all the way upto CAT but if in between I get busy otherwise, I may not able to upload questions and videos and thus would warn people against using this series as their primary source of study.

Question for 2nd April, 2020 - Level Basic


Exactly four out of the eight friends named Trump, Obama, Bush, Clinton, Reagan, Carter, Nixon and Kennedy have a number of gold coins with them. The number of gold coins with these four friends can be 1, 2, 5 or 10. Each of those four friends has different number of gold coins with them. The remaining four friends do not have any gold coin with them.

Six individuals, named A, B, C, D, E and F are asked to predict the names of the friends having different number of gold coins with them. The following table shows the predictions made by these six individuals:

           10 Coins         5 Coins         2 Coins       1 Coin

A         Kennedy          Trump          Reagan      Obama

B          Clinton          Kennedy          Bush         Carter

C           Bush              Reagan         Trump       Obama

D          Carter             Clinton          Nixon       Kennedy

E           Nixon             Obama         Clinton       Reagan

F           Carter              Nixon           Obama        Bush


Further, the following points are known:

Out of the four names mentioned by each of these six individuals, exactly two names contained the names of the friends who had gold coins with them and the remaining two names were of the friends who did not have any gold coin with them. 

Each individual correctly predicted the names of the two friends who had gold coins with them. However, the number of coins predicted by each individual with these friends was swapped. For example, if one friend (named say ‘P’) has 10 gold coins and the second friend (named say ‘Q’) has 5 coins, there is exactly one individual who predicted that P and Q had gold coins with them. However, that individual predicted that ‘P’ had 5 coins and ‘Q’ had 10 coins (i.e. exactly opposite of the number of coins actually with them).

Q1) The exact number of gold coins with how many of the four friends can be uniquely determined?

a) 0                  b) 1                      c) 2                     d) More than 2

Q2) Out of the four friends predicted by C, who are the two friends who had gold coins with them?

a) Bush and Reagan                    b) Reagan and Trump       

c) Trump and Obama                  d) Bush and Obama

Q3) What was the sum of the number of gold coins with the friends predicted by D?

a) 15                 b) 7                       c) 3                    d) 6

Q4) How many of Trump, Nixon, Bush and Obama had at least one gold coin with them?

a) 0                   b) 1                       c) 2                    d) More than 2
