- there is 7 numbers 5,5,9,9,6,6,5,0
and the number which is going to generate must be greater than 60,00,000 as per the above questions.
now draw 7 space just like this : _,_,_,_,_,_,_ we can not put 0 or 5,5 as first digit. because it will be less than 60,00,000 so there is only 4 numbers that may have first place i.e (9,9,6,6) now the next digit could be anything from the set except the first digit
so 4*6*5*4*3*2*1/2*2*2 =360 . we have 2 fives 2 nines 2 sixes that why I divided the equation - 9 years agoHelpfull: Yes(10) No(1)
- For data sufficiency
D)both are insufficient to ans the question - 9 years agoHelpfull: Yes(2) No(0)
- for data suffcncy both stmnts r requires
4+4+3=11
4+3+3=10 - 9 years agoHelpfull: Yes(1) No(4)
- ans is 180
(2*6*5*4*3*2*1)/2!*2!*2! - 9 years agoHelpfull: Yes(0) No(5)

- 9 years agoHelpfull: Yes(0) No(0)
- 540 ways
Total 7 digits no - nos starting with 0
=7!/(2!*2!*2!)- 6!/(2!*2!*2!) - 8 years agoHelpfull: Yes(0) No(2)
