This question is dedicated to Parbatya, the Guniess who is always there with a correct answer for my pirated mathematical problems.

Parbatya's special mobile number has ten digits, beginning with 0.

When I tap it into my phone keypad, I note that-
- no two adjacent digits of his number are in the same column or row of my keypad
- the 2nd digit is even
- the 4th digit is odd, and 7 different from the 3rd digit
- the 5th and 6th digits differ by 1
- the last 3 digits are in ascending order

My keypad is laid out as shown:

123
456
789
*0#

What is his number?

I think it looks fine, as OcRam didn't mention about 7th digit.

One more mathematical question: You have eight balls, all of the same size. 7 of them weigh the same, and one of them weighs slightly more. How can you find the ball that is heavier by using a balance and only two weighings?

If you use all the numbers from 0-9 and not repeat the same number more than once, then one of the solutions might be the following:

062-9438-157

choose six balls and weigh three against three, if they weigh the same, you have another weighing for the remaining 2 balls and you can find the heavier one if they don’t weigh the same, from the group of 3 which was heavier, choose any 2 balls and weigh them: if they weigh the same, the remaining ball is the heavier one; otherwise you just found the heavier one by weighing the 2 chosen balls.

OcRam,

oh! you gave my phone no here in sajha?Only one digit is off from the list. And I have to say that you are the teacher while I am still learning at puzzles although my older mind is trying to avoid mathematical exercises.
