`        The no. Of six digit number that can be formed from tje digits 0,1,2,3,4,5,6&7 so that digits do not repeat and the terminal digits are even`
3 years ago

```							the total number form which the 6 digit number should be made are 8out of which 4 are even (0,2,4,6) and these are to be arranged in the terminal points (end points)hand hence we have to arrange 4 numbers in 2 places (even             even)hence total numbers of ways we can do this are 4!/(4-2)! = 4*3 = 12now we have 12 cases with terminal points occupied with two numbers so we have 4 places remaining with 6 numbers remaining and the number of ways we can do this are 6!/(6-4)! = 6*5*4*3 = 360  hence we have 360 solutions in each case and there are total 12 cases therefore the total number of 6-digit number that satisfies our condition =360*12 =

```							 OOH I am sorry for a mistakeActually I considered that all numbers can occupy first position ( THIS                ) but it cannnot be occupied by 0 so only the number of cases will be affected that is the first place will have 3 possible cases(2,4,6) and last place will aslo have 3 possible cases(0,2,4,6 out of which oneis already in first place)so our cases reduces to 3*3 = 9 instead of  12but then also the answer will be 360*9 =  and please don’t call me sir.

```							i think that the answer will be 720only is “0” is not incuded And for that question the solution will belet the number be a b c d e f (say)a = 3 numbers possible (2,4,6)f = 2 numbers possible (2,4,6 out of which one has occupied “a”)and then it goes on decreasing b = 5 numers possiblec = 4 numbers possibled = 3 numbers possiblee = 2 numbers possibleand hence the answer should be 3*2*5*4*3*2 =  previous
