The largest number that also satisfies Statement I is :

651 ==> 6x5x1 = 30 ( 1 is also a factor of 30, so is 6 )

So, we end up with YES and NO for Statement I - INSUFF

It's not A.

Statement I:
Insufficient
3*2*5=30
6*5*1=30

Statement II:
Insufficient
3+2+5=10
6+3+1=10

combined, C.
Digits have to 3,2,and 5 which is < 550.

1 - 5*6*1 or 5*2*3
560 or 650 - INSUFF
2. 811 or 118 INSUFF

C - 5+6 11 is out so must be 2,3, and 5 in any order < 550.

I'm getting C.

Stat 1:

Number could be 516; prod. = 5*1*6 =30
Number could be 615; prod = 6*1*5 = 30

Insuff.

Stat 2:

Number could be 901 or 109; insuff.

Stat 1 & 2:

Number could be 523 or 253. Point being the number has to be less than 550. We cannot have a number greater than 550 which satisfies 1 & 2.
