About This Set
Each of these 25 questions needs a single method: a number series, someone joining, leaving or being replaced, a wrong entry, cricket or target marks, two groups combined, or a family's ages. They come in mixed order, so first see what has changed (the count, the total, or the time) and then pick the method. Allow about 25 minutes and finish all of them before you check. With fewer than 20 right, go back to the topic section for each one you missed before Practice Set 2.
