big boxes

by sanju09 » Fri Feb 27, 2009 5:22 am
A company prepares a consignment by packing 20 compact discs in each small box. If the same consignment was to be packed in big boxes with 50 discs in each box, how many big boxes would be required?

(1) The consignment is for a total of 6000 compact discs.

(2) The ratio of the number of big boxes to the number of small boxes is 2 : 5.

IMO A

Total CD = 6000
CD/big box =50.

big boxes = 120.

A is suff.

From B, we only know the ratio of boxes.
Hence insuff
