Can someone tell how to solve this on calculator?

CF worksheet

CF0 = -270 C01=30 F01 = 9,9999 (it’s not infinity, but close enough :man_shrugging: ETA: the calculator won’t accept 10,000, but it’ll take 9,999 :+1:)
CPT IRR (I don’t have my calculator on me right now :man_shrugging:)

With some simple algebra

0 = -270 + 30/IRR
270 = 30/IRR
IRR = 30/270
IRR = 0.1111111111

10,001 would be closer. :wink:
