"Guess how many popcorn kernels are in the jar and win an iPad2 compliments of Charles Kendall Freight."  That was the aim of the competition at the WCA Sino conference in Shanghai last week which went on to be won by Richard Lu of CDS Logistics Ltd.  Mr Lu was completely surprised as he'd never won anything before and when asked how he'd reached his guess of 8250 (the actual figure was 8280), he replied that he'd used a mathmatical formula!  Peter Sunderland, MD of CKF extended his congratulations to the winner at the formal presentation on stage with David Yokeum from the WCA - see picture.
