**Given:**

The Santa complete 50% of the work = 9 days

**Formula used:**

W = T × E (Where W = Work, T = Time, and E = Efficiency)

**Calculation:**

⇒ Santa complete 50% of the work then the remaining work = 1 - 1/2 = 1/2 = 50%

⇒ 50% of the work completes by Banta = 15 days

⇒ The Banta can complete the work alone = 2 × 15 = 30 Days

**∴ The required result will be 30 days.**
