Solution

The correct option is C 2550
Ans: Extra cost of the other phone = Rs 330. When she buys a second phone she saves 275*0.8 = Rs 220. the overheads are 330-220=Rs 110.

For each minute above 2000, she will save 20 paise. So by using for 550 minutes, Rs 110 will be saved. Thus at 2550 minutes, both costs are equal. Answer is option (c)

Using the phone at her desk, Sylvia in Corporate Sales consistently generates a very steady $$$ 1500 per hour in gross revenue for her firm. After all of her firm's costs have been subtracted, Sylvia's sales amount to $$$ 100 in bottom line (net) profits every 15 minutes. At 10:00 a.m. one day the desk phone Sylvia uses to make her sales calls breaks. Without the phone Sylvia cannot make any sales. Assume that Sylvia's regular schedule is to begin making sales calls at 8:00 a.m. Assume she works the phone for four hours, takes a one hour lunch exactly at noon, and then returns promptly to her desk for four more hours of afternoon sales.
