1. For any positive integer n, n! is the product of all positive integers less than or equal to n. Quantity A = 20! / 17! Quantity B = 80! / 78!   Quantity A is greater   Quantity B is greater   The two quantities are equal   The relationship cannot be determined from the information given   Hint Hint       2. a, b, c and d are four consecutive integers. Quantity A = The arithmetic mean of a and d Quantity B = The arithmetic mean of b and c   Quantity A is greater   Quantity B is greater   The two quantities are equal   The relationship cannot be determined from the information given   Hint       3. 0 < a < 1 Quantity A = a3 Quantity B = a2   Quantity A is greater   Quantity B is greater   The two quantities are equal   The relationship cannot be determined from the information given   Hint       4. 2 < z < 4 Quantity A = π2z3 Quantity B = π3z2   Quantity A is greater   Quantity B is greater   The two quantities are equal   The relationship cannot be determined from the information given   Hint       5. m is a negative number. Quantity A = m3 Quantity B = -m2   Quantity A is greater   Quantity B is greater   The two quantities are equal   The relationship cannot be determined from the information given   Hint       6. y is a positive integer less than 200. Quantity A = The number of multiples of 3 between y and 200. Quantity B = The number of multiples of 5 between y and 200.   Quantity A is greater   Quantity B is greater   The two quantities are equal   The relationship cannot be determined from the information given   Hint       7. In the correctly worked out addition problem given below, each letter represents a different digit. BC + BC = CAA Quantity A = A Quantity B = 6   Quantity A is greater   Quantity B is greater   The two quantities are equal   The relationship cannot be determined from the information given   Hint
