can u help on clearly how to solve it in the excel sheet

f. What is the regular payback period for these two projects? Project A Time period Cash flow Cumulative cash flow 0 (375) (375) 1 (300) (675) 2 (200) (875) 3 (100) (975) 4 600 (375) 5 $600 225 6 $926 1,151 7 ($200) 951 Intermediate calculation for payback Payback using intermediate calculations Project B Time period Cash flow Cumulative cash flow Intermediate calculation for payback Payback using intermediate calculations Payback using PERCENTRANK 0 (575) (575) 1 $190 (385) 2 $190 (195) 3 $190 (5) 4 $190 185 5 $190 375 6 $190 565 7 $0 565 Ok because cash flows follow normal pattern. g.
