Surya can complete a work in 8 days and Mathivennila can complete the same work in 12 days. If both work together, how many days will they take to complete the work?

Explanation

Step 1: Find daily work rate of Surya and Mathivennila

Step 2: Find combined 1-day work

LCM of 8 and 12 = 24

So, together they do ( \frac{5}{24} ) of the work in 1 day.

Step 3: Find total days to complete 1 work

✅ Answer

4.8 days (Option C)
