Answer 2

Calculation of the Number of Days

To calculate the number of days it would take for the painter to complete the job if they painted 2 more desks per day than the norm, we need to determine the norm and the total number of desks.

Given: - The painter painted 48 desks in 4 days. - The painter's norm is not provided.

To find the norm, we can divide the total number of desks painted by the number of days it took to paint them: - Norm = Total number of desks / Number of days

Using the given information, we can calculate the norm: - Norm = 48 desks / 4 days = 12 desks per day.

Now, we need to calculate the total number of desks to be painted. Since the total number of desks is not provided, we cannot determine the exact number. However, we can use the formula below to calculate the number of days it would take to paint any given number of desks:

- Number of days = Total number of desks / (Norm + 2)

Let's assume the total number of desks to be painted is 'x'. Using the formula above, we can calculate the number of days it would take to paint 'x' desks: - Number of days = x desks / (12 desks per day + 2 desks per day) = x / 14 days.

Therefore, the painter would take x / 14 days to complete the job if they painted 2 more desks per day than the norm.

Please note that without the total number of desks to be painted, we cannot provide an exact number of days.
