a man worked in february 2009.he was paid rs 500 perday and rs 100 were deducted when he was absent . find number of days he was presentif was paid rs9100 as salaryfor the manth.

Absent: X days.

Worked: 28-x days.
$9100/($500/day) =

Disregard the first 2 lines.

To find the number of days the man was present, we can set up an equation using the given information.

Let's assume that the number of days the man was present is 'p'. Since he was paid Rs 500 per day and Rs 100 were deducted when he was absent, the total earnings for the month can be calculated as follows:

Total earnings = (Payment per day * Number of days present) - (Deduction per absence * Number of absences)

Rs 9100 = (Rs 500 * p) - (Rs 100 * (30 - p))

Simplifying the equation, we have:

Rs 9100 = Rs 500p - Rs 100(30 - p)

Rs 9100 = Rs 500p - Rs 3000 + Rs 100p

Rs 9100 + Rs 3000 = Rs 500p + Rs 100p

Rs 12100 = Rs 600p

Now, we can solve for 'p' by dividing both sides of the equation by Rs 600:

p = Rs 12100 / Rs 600

p ≈ 20.17

Since we cannot have a fractional number of days, we can round down to the nearest whole number. Therefore, the man was present for approximately 20 days.
