Question

We have four papers. On each of them there is a number on one side and some information on the other. The numbers on the papers are 7, 2, 15, 5. The information on the papers is given below in random order.

i. A number divisible by 7 

ii. A prime number 

iii. An odd number 

iv. A number greater than 100

If the number on every paper is mismatched with the information on its other side, what is the number on the paper which says ‘A number greater than 100?

Answer 1

Analysis	Reason	Outcome
The paper having information (iii) ‘an odd number’ can be mismatched with the number ‘2’ from the other available options.	Only the number ‘2’ is an even number, while the rest are odd numbers.	The number ‘2’ and (iii) ‘an odd number’ will appear on the opposite sides of the same paper.
Now, we are left with the numbers 7, 15 and 5. The paper having information (i) ‘a number divisible by 7′ can be mismatched with the number ‘5’.	The number ‘5’ is not divisible by 7.	The number ‘5’ and (i) ‘a number divisible by 7’ will appear on the opposite sides of the same paper.
Now, we are left with the numbers 7 and 15. The paper having information (ii) ‘a prime number’ can be mismatched with the number ‘15’.	The number ‘15’ is not a prime number.	Hence, the number ‘15’ and (ii) ‘a prime number’ will appear on the opposite sides of the same paper.
