The Decimal Number System is also called "Base 10", because it is base

1.	The Decimal Number System is also called "Base 10", because it is based on the number 10. It has 10 symbolsas 0,1,2,3,4,5,6,7,8,9. But notice something interesting: there is no symbol for "ten". "10" is actually twosymbols put together, a "1" and a "0"In decimal you count "0,1,2,3,4,5,6,7,8,9,..." but then you run out of symbols! So you add 1 on the left and thenstart again at 0:10,11,12,...Now similar to this we can have more number systems like binary where we use only 0 and 1 with the sameconcept as it was in decimal:-0 -> 0, 1 -> 1,2 -> 10, 3 -> 11,4 -> 100. .. .. 15->1111.. and so on.Other than binary and decimal we haveoctal number system which uses:- {0,1,2,3,4,5,6,7)hexadecimal:-They look the same as the decimal numbers up to 9, but then there are the letters("A", "B", "C","D", "E", "F") in place of the decimal numbers 10 to 15. For ex A5 = 165, BO = 176If a number X when represented in octane, decimal and hexadecimal has the same representation then howmany different X are possible?
