My approach:
A - Number of pieces X [9.XY-9]: INSUFF
B - 18 X [A.XY-A]: INSUFF

A&B together: 18 X [9.XY-9]; SUFF-----C

I'm wrong as per OA....why?

It should be E.

From stmt1: it is not clear what the actual weight of the piece is. It is < 9.5 that means, it could be 1, 2, 3, 4, .....anything.

i actually disagree i think ans should be C..

look worst case all meats weigh 9.4 and get rounded to 9?

which means 9.4*18= lets for argument sake round 18 to 20, then worst case actual weight would be 8lbs heavier than estimated..

either way the estimated weight would be less than 10lb..

Thanks for pointing out. I overlooked it.

However, the answer should be B. Irrespective of the weight of individual piece, if the weight is >= x.5, it will be rounded to the next integer and if it is <x.5 then to the lower integer and since there are only 18 pieces, in either case the weight difference will be < 10 lbs.

i agree it should be B..

i have a bad habit of forgetting what the stupid question was..grrr

B is sufficient..cause 18*(0.4) <10Lbs
