chill sir, can you explain how you can infer that a1+a2+a3+...+a7 is divisible by 3 from 3N is divisible by 3... ? each of a1,a2, a3.... a7 is multiplied by a different number?

why can't we select 0 in the second case when 0 can be selected in the case a>b>c even if 0 is selected when ab>c... okay since the first digit cant take 0 it is 9 c2.. right! i get it

okay there's a mistake there... if i take it this way.. the last digit can be filled in 0-7 ie 8 ways the first one can be filled in 2-9 i.e.,8 ways and the middle one can be filled in 1-8 i.e., 8 ways... so 8.8.8... what's wrong here? hope you are getting what i am trying to get clarified??

bhai, i have a little doubt in this question... since a 3 digit number is needed.. _ _ _ i can fill the last space in 10 ways the first space can be filled in 7 ways and the second in 9 ways i.e., 10*9*7 *2 for ascending and descending.. now where is my understanding wrong? please help
