Praveen can complete a work in 12 days and Varun can complete the same work in 16 days. If both work together, how many days will they take to complete the work?

Given

Praveen's time to complete work = 12 days Varun's time to complete work = 16 days

Explanation

Step 1: Find daily work rate of Praveen and Varun

Step 2: Find combined 1-day work

LCM of 12 and 16 = 48

So, together they do ( \frac{7}{48} ) of the work in 1 day.

Step 3: Find total days to complete 1 work

✅ Answer

Approximately 6.86 days (Option B: 7 days)
