SSC CHSL 31st May 2022 Shift-3

- The ratio of time taken by Anamika to Bani is 1:3.

- This means Anamika is faster, completing work in 1/3rd the time Bani takes.

- Let Bani's days to complete work = 3x; Anamika's = x.

- It's given Anamika finishes in 40 days less: 3x - x = 40.

- Solving gives x = 20.

- Anamika takes 20 days, Bani 60 days.

- Working together: 1/20 (Anamika's rate) + 1/60 (Bani's rate).

- Combined rate = 1/15.

- Together, they complete work in 15 days.

The correct answer is Option 3: 15.
