Q:

What 5 - digit number has the following features :

If we put the numeral 1 at the beginning, we get a number three times smaller than if we put the numeral 1 at the end of the number?

Answer

Let the 5 digit number be represented by abcde.


Then the 6 digit number, 1abcde x 3 = abcde1 (another 6 digit number)


Now let Y = abcde


Then (100000 + Y) x 3 = (Y x 10) + 1


300000 + 3Y = 10Y + 1


7Y = 299999


Y = 299999 ÷ 7 = 42857

Puzzle : Identical Balls

There are 8 identical balls. In that one of the ball is overweight. There are only two chances to weigh in the weighing machine. How to find the overweight ball?

Answer

First weigh 3 against 3 balls. If the ball contains among these six balls, then take the three balls which weighed over, and weigh the ball 1 against 1. If the balls are not equal and any one of the ball weighs more, that is the overweight ball, else the one among the three which is not weighed is the ball. If the 3 against 3 balls were equal, then weigh the 2 balls, then the overweight ball will be found.
