Sai can do a piece of work alone in 50 days. Ria is 25% more efficient than Sai. What is the number of days that Ria will take to

do the same piece of work alone?

30 days

60 days

40 days

56 days

- Sai can complete the work alone in 50 days.

- Ria is 25% more efficient than Sai. This means Ria can do 125% of the work Sai does in the same time.

- To find how many days Ria takes, we need to determine her efficiency relative to Sai.

- If Sai's work rate is 1/50 of the work per day, Ria's work rate is 1.25 times that.

- Ria's rate = 1.25 x (1/50) = 1/40 of the work per day.

- Therefore, Ria will complete the work in 40 days.

- Correct Answer: Option 3 - 40 days
