ITPEC IP April 2026 — Question 100 of 100
3.3 years — divide the initial investment by the annual net financial benefit.
Rebuilding saves 5 − 4 = 1 million yen in operating cost each year and creates 2 million yen of new annual profit. Total annual benefit is 1 + 2 = 3 million yen. Payback period is 10 ÷ 3 = 3.333..., rounded to one decimal place: 3.3 years.
Answer (b)
Why not others: (a) 2.5 uses the new operating cost as benefit; (c) 5.0 counts only new profit; (d) 10.0 counts only the 1-million cost saving.
Key rule: Payback period = initial investment ÷ annual incremental cash benefit, including both savings and new gains.
