This set covers the classic counting problems used in aptitude tests. You will arrange the letters of words such as LEADING, OPTICAL, CORPORATION and MATHEMATICS with vowels kept together or in fixed positions, adjusting for repeated letters. Committee questions ask how many ways to choose a group with a minimum number of men or women, which needs combinations added across cases. Digit problems ask how many three-digit numbers divisible by 5 can be formed without repetition. Knowing when to multiply, when to add and when to divide by repeated factorials is the core skill.

A permutation counts arrangements where order matters, such as seating people in a row. A combination counts selections where order does not matter, such as choosing a committee. For the same items, there are always at least as many permutations as combinations.
