the second digits tells you how many ones there are in the number,

the third digit tells you how many twos there are in the number, etc.

For example, with the number 21200, there are 2 zeros, 1 one, 2 twos,

0 threes and 0 fours. What is the required eight digit number?

70000000 is wrong - since It started with seven, the 8th digit must be 1
42101000 is the only number I can think of right now, but there may be other possibilities.

enable the selection be xyz. From the given assertion: I deduce the fact below. (a million) y = z + 5 (2) x = y - 8 (3) 0 = < y,z < 10 (through fact they're single digit each and every) (4) 0 < x < 10 (so far the numbers is a three digit, subsequently this is a non - 0 numbers) From (a million), (2), we get: y = z + 5 ........ (a million) x = y - 8 ......... (2) From (2) x = y - 8 y = x + 8 ............. equation(5) by using equating equation (a million) and equation (5) y = y z + 5 = x + 8 x = z + 5 - 8 x = z - 3 ........................ equation (6) From (4), (6): z - 3 > 0 ? z > 3 subsequently, z > 3 From (a million), (3): z + 5 < 10 z = < 10 - 5 ? z < 5 when you consider that 3 < z < 5, subsequently z = 4. applying (a million), (2), we get: y = 4 + 5 = 9 x = 9 - 8 = a million ? x = a million, y = 9, z = 4 through fact the selection is xyz subsequently the selection is 194.
