About This Set
These 25 questions are at Tier 1 level and use SSC's kind of wording. The wrong options are the answers students really get: the subtraction answer in replacement, the swapped alligation ratio, the cross done on a selling price. Removal and replacement, adding water for a new ratio or percentage, and mixing for profit get the most questions, since recent papers ask these three often; the other types are mixed in. Take about 25 minutes and attempt every question before you check. With 20 or more right, move on to Practice Set 3.
