Therefore, the total of the salaries combined should be between: 4*5 + 20 = 40 and 5 + 20*4 = 85 Of choices given: 1) 5*7.5 = 37.5 --> out of range 2) 5*9 = 45 --> good 3) 5*16.75 = 83.75 --> good Only 2 and 3 are possible, therefore E _________________ Best Regards, Paul Senior Manager Joined: 30 Aug 2003 Posts: 325 Location: dallas , tx Followers: 1 Kudos [?]: 9 [0], given: 0 [#permalink] 16 Jan 2004, 12:08 4*5 + 20 = 40 and 5 + 20*4 = 85 how did u get this part? _________________ shubhangi GMAT Club Legend Joined: 15 Dec 2003 Posts: 4309 Followers: 29 Kudos [?]: 234 [0], given: 0 [#permalink] 16 Jan 2004, 12:32 We are trying to find the range of the total salaries. If the salaries were between 5 and 20 inclusive, then we try to find the extreme values. Therefore, I assumed 2 scenarios. 1- 4 employees are paid the maximum (20$) and there is one who is paid 5$--> 5 + 20*4 = 85 2- 4 employees are paid the minimum (5$) and there is one who is paid 20$--> 4*5 + 20 = 40 _________________ Best Regards, Paul Senior Manager Joined: 30 Aug 2003 Posts: 325 Location: dallas , tx Followers: 1 Kudos [?]: 9 [0], given: 0 [#permalink] 16 Jan 2004, 12:38 thanks paul..understood _________________ shubhangi Intern Joined: 01 Dec 2003 Posts: 35 Location: infront of my LCD Followers: 0 Kudos [?]: 0 [0], given: 0 [#permalink] 16 Jan 2004, 18:05 Shouldnt the range be 5*5 = 25 5*20 = 100 Why doesnt 1 work?

How can you get 40 as a min? If the 5 employees each earn$5/hr then together they earn 25/hr. Right?

All 5 cannot earn 5$. At least one has to earn 20$ because it is stated that that range of salaries is 5 to 20\$.
