Is the average (arithmetic mean) of 5 different positive integersat least 30 ? (1) Each of the integersis a multipleof 10. (2) The sum of the 5 integers is 160. 选D 我想问(1)中的each of the integers is a multiple of 10 这个multiple可以是小数倍么?10的1.5倍是15也是整数啊?
D? If you consider the first five positive multpiles of 10,10, 20, 30, 40, 50. The average is 30. Statement 1 is suff Statement 2 is sufficient. As average = 160/5
