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. n(n + 2)(n + 4) = 480 Quantity A = n + 2 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       3. yz < 0 Quantity A = (y − z)2 Quantity B = y2 + z2   Quantity A is greater   Quantity B is greater   The two quantities are equal   The relationship cannot be determined from the information given   Hint       4. Andrew stitches shirts thrice as fast as Bill. Bill charges 40% more per shirt than Andrew. Quantity A = The amount Andrew earns in 8 days Quantity B = The amount Bill earns in 15 days   Quantity A is greater   Quantity B is greater   The two quantities are equal   The relationship cannot be determined from the information given   Hint       5. 11y4/(3y2) = 11/3 Quantity A = y Quantity B = 1   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 > 0 Quantity A = 100 y Quantity B = 100 / y   Quantity A is greater   Quantity B is greater   The two quantities are equal   The relationship cannot be determined from the information given   Hint       7. 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
