Arrival of machines for repair in a maintenance shop follows a Poisson distribution at a rate of one per 18 hours. The time to repair follows an exponential distribution with Mean Time “To Repair (MTTR) of 14 hours. If the productivity loss is Rs. 22,500 per hour, then the total expected loss of productivity due to machine breakdowns, in Rs., is
(a) 78,750 (b) 1,01,250
(c) 11,81,250 (d) 14,17,500
