About This Set
Each of these 25 questions needs one basic method, used once: LCM units, pair data, efficiency, men-days, alternate days, wages, or a tank with an outlet or a leak. The sums are short, so most of the effort goes into picking the method. Take about 25 minutes and finish the set before you check any answer. If fewer than 20 are right, reread the topic section behind each miss before you start Practice Set 2.
