To calculate the total amount, we need to multiply the number of times (50) by the value per time (5 paise) for the given number of days (50).
Total amount = (Number of times) * (Value per time) * (Number of days)
Total amount = 50 * 5 paise * 50 days
To simplify, we can convert the value of 5 paise to rupees. Since 100 paise make 1 rupee, 5 paise is equal to 5/100 rupees, which is 0.05 rupees.
Total amount = 50 * 0.05 rupees * 50 days
Calculating this expression, we get:
Total amount = 125 rupees
Therefore, the correct answer is option D) 125 rupees.
