Cost of Material Rs. 40000, Rate of wages per worker is Rs. 2 per hour for normal duty and Rs.4 per hour for overtime duty, Man hour per day of normal duty is 8 hour, No. of holidays per month without wages is 5 days, total overhead expenses is Rs. 10000. The workers are paid overtime for 300 hours. Calculate the total cost per month.

Given Data:

Total No of Workers = 100

Cost of Material= Rs 40,000

Overhead Cost = Rs 10,000

Wage Rate (Normal duty) = Rs 2/hr

Wage Rate (Overtime duty) = Rs 4/hr

Normal duty hours = 8 hrs/day

Number of holidays per month = 5 days

Number of overtime hours = 300 hrs

Total number of day in April = 30 days

Number of working days in April = 30 - 5 = 25 days

Total Worker wage for normal duty = 8 x 2 x 30 x 100 = Rs 48,000

Total Worker wage for overtime duty = 300 x 4 = Rs 1,200

Total cost per month = Cost of Material + Overhead Cost + (Worker Wage + Overtime Wage) = 40,000 + 10,000 + 48,000 + 1,200

Total cost per month = Rs 99,200
