#302 - Logical Number Problem

According to number theory of mathematics , a perfect number is a positive integer that is equal to the sum of its positive divisors excluding the number itself.
For example :
6 => 1+2+3
28 =>1+2+4+7+14

I know one more number that is a perfect number and contains not more than 2 digits (i.e 496 won't be consider as it contains 3 digits).

Find the number ?

Logical Number Problem

12=> 1+2+3+6

cannot be 1 (as number cannot be included)

#303 - Logical Interview Puzzle

Can you divide numbers from 1 to 9 (1 2 3 4 5 6 7 8 9) into two groups so that sum of the numbers of each group is equal?

Note: 9 cannot be turned over to make it 6.

Logical Interview Puzzle

1 2 3 4 5 9 and 7 8 9

sum of numbers 1 2 3 4 5 6 7 8 9 is 45 , so numbers cant be split into 2 equal parts.
I know i cant turn 9 upside down and make it 6 but i can turn 6 to make it 9.

#304 - Logic Puzzle Problem

Like an usual car, my new i10 car has 5 wheels(2 front + 2 Rear + 1 spare).
The rear wheel of the car will wear out after 21000 kilometers and the front wheel will wear out after 29000 kilometers.

What is the maximum distance I can cover assuming changing of wheels is not an issue?

Logic Puzzle Problem

Maximum distance: 30,450 kilometers.

For every 5 kilometers driven using this rotation, each tire will lose (2/29000)+(2/21000) of its tread.So, suppose we drive 5*N kilometers like this. Then, each tire will lose 2*N*((1/29000)+(1/21000)) of its tread. We wish to determine N so that the latter expression gets to be 1, representing all of each tire's tread. That happens when N=6090, which is when 5*N (the total kilometers were driven) is 30,450.

#305 - Card Riddle

I have mixed 13 decks of cards.
What is the minimum number of cards must be taken out from the above mixed cards to guarantee at least one 'four of a kind'.

Card Riddle

13 x 3 + 1 = 40

Explanation:

The number of decks is irrelevant i.e any number of decks can be mixed and still the answer would be same.
Any card drawn will be a Ace,2,3,4,5,6,7,8,9,10,Jack,Queen or King, so there are 13 possibilities each time a card is drawn.
The fastest and luckiest way would need just 4 cards of the same kind.

The slowest way is our solution as it will guarantee a four of a kind.
i.e draw 3 of each kind =>39 cards will be fetched. now next card will guarantee 4 of a kind.
