This page is for fun. I am writing this page so that freshers as well as seniors can think logically.I don’t think freshers need to panic during 1st round of interview –the written test where the puzzle use to puzzle them.Everybody if we try to solve 5 puzzles per day and 60 days of preparation is taken, that is more than enough to crack an interview.
Lets talk about Puzzle
2nd digit is the sum of 1st and 3rd.And that number is divisible by 2,3,6,7. What is that number?
say the number is xyz
and it is divisible by 2,3,6,7 i.e any multiplier of 2*3*6*7=42 that will satisfy the conditions
the three digit multiplier of 42
so the required number is 462
After pausing a moment, he replied, “Well! If I divide the coins into two unequal numbers, then 37 times the difference between the two numbers equals the difference between the squares of the two numbers.”The wife looked puzzled. Can you help the merchant’s wife by finding out how many gold coins do they have?
Let, total no. of gold coins= x
Let, y and z be two numbers such that x = y + z (y not equal to z)
Given, 37(y – z) = (y^2) – (z^2)
Therefore, 37(y – z) = (y + z)(y – z)
Hence, total no. of gold coins= x = y + z = 37
