same problem but mene website par dekha yhi question usme factorial se kiya tha jisme esa tha ki no of ways toh arrange vowel is 2! and no of ways toh arrange consonent 3! therefore 3! x 2! = 3*2*1 x 2*1 = 12 mujhe toh smaj nhi aaya ager tumhe aajye toh dekh lo
3:17:11 When I saw this question, I paused the video and started solving, and I got the answer as D5 +D4, but sir got the answer D6/5, but then I realized both are actually equal, D5 +D4 = 53 = D6/5, that mean I did correct just my method was different from that of sir's....
