n4*4=4n.
1) if n is single digit number then we get n will be fraction.
2)similarly tru for n as 2,3,4 digit numbers we won't get.
3) let n=abcde
then
abcde4*4=4abcde

which by solviving we get 13*abcde=133328
so abcde=10256.

thus 102564*4=410256

Its similar to saying 24 * 4 = 42 i.e (2*10 + 4) * 4 = 4*10 + 2
.. I know they are not equal :)

Given: n4 * 4 = 4n
=> (10n + 4) * 4 = 40 + n
=> 40n + 16 = 40 + n
=> 39n = 24
=> n = 24 / 39

yup , its a fraction !! Source: CoolInterview.com

	Three salesmen went into a hotel to rent a room. The manager stated that he had only one room left, but all three could use it for $30.00 for the night. The three salesmen gave him $10.00 each and went up to their room. Later, the manager decided that he had charged the salesmen too much so he called the bellhop over, gave him five one-dollar bills, and said: 'Take this $5.00 up to the salesmen and tell them I had charged them too much for the room'. On the way up, the bellhop knew that he could not divide the five one-dollar bills equally so he put two of the one-dollar bills in his pocket and returned one one-dollar bill to each of the salesmen. This means that each salesman paid $9.00 for the room. The bellhop kept $2.00. Three times nine is 27 plus two is 29....... What happened to the extra dollar?	View Answer

	A number is called a palindrome when it is equal to the number you get when all its digits are reversed. For example, 2772 is a palindrome. We discovered a curious thing. We took the number 461, reversed the digits, giving the number 164, and calculated the sum of these two numbers: 461 164 + ------- 625 We repeated the process of reversing the digits and calculating the sum two more times: 625 526 + ------- 1151 1511 + ------- 2662 To our surprise, the result 2662 was a palindrome. We decided to see if this was a pure coincidence or not. So we took another 3-digit number, reversed it, which gave a larger number, and added the two. The result was not a palindrome. We repeated the process, which resulted in another 3-digit number which was still not a palindrome. We had to repeat the process twice more to finally arrive at a 4-digit number which was a palindrome. What was the 3-digit number we started with the second time?	View Answer
