Three men run a business together.

The proportion of the profit they each get at the end of the month is based on the proportion of the funds they have invested in the business.

The April profit is shared out so that Al gets one third, Bob gets one half and Chuck gets one sixth.

In May, Des joins the group, investing half as much as Bob invested.

What share of the profit can Des expect to get?
