Mental Ability — Pack 04
Aspirants preparing for the Lower Division Clerk (LDC) and Secretariat Assistant exams can benefit from this Mental Ability practice set, which covers topics such as calculating means, finding the highest common factor (H.C.F.) of numbers like 36 and 264, determining percentage decreases, and identifying prime numbers, including the smallest 3-digit prime. With 25 medium-difficulty questions, this set is ideal for use after revising basic arithmetic and logical reasoning chapters to test recall of concepts like H.C.F. and percentage change. For instance, understanding that the mean of a series like 5, 10, 15, 20, 25 is 15, or that the H.C.F. of 36 and 264 is 12, can help build confidence. Review explanations after submission to lock weak areas, such as family relationship puzzles like determining Y's relation to X, to optimize your practice.
