The question is in Hindi and seems to involve solving a work-time problem based on the image provided. Let me analyze and solve it.

The problem involves workers and machines. Here's a breakdown of the question:

1. 3 machines take 4 days to complete the work.
2. How many days will it take for 6 machines to complete the same work?

Step-by-Step Solution:

• Step 1: Calculate the total work done.

  If 3 machines complete the work in 4 days: $\text{Total work} = 3 \times 4 = 12 \, \text{Machine-Days (MD)}.$

• Step 2: Work done by 6 machines in 1 day.

  In 1 day, 6 machines will complete: $\text{Work done by 6 machines in 1 day} = 6 \, \text{MD}.$

• Step 3: Days required for 6 machines to complete the total work.

  To complete 12 MD of work: $\text{Days required} = \frac{\text{Total work}}{\text{Work done by 6 machines per day}} = \frac{12}{6} = 2 \, \text{days}.$

Thus, 6 machines will complete the work in 2 days.
