As these three strategies P, Q and R are independent so these will cut cost one after the other. If initial cost is Rs 100, then 20% cost is cut after initializing strategy P, then cost will remain 80% = 80 further 30% cost is cut after strategy Q, then cost will remain 70% of 80 = 56 further 10% cost is cut after strategy R, then cost will remain 90% of 56 = 50.4 Thus final cost remains 50.4 % of the original cost. Hence net saving is 100 - 50.4 = 49.6 %.Related questions
