I did the question in the below method. K makes 2x omelette in 50 mins then in 1 min = 2x/50 Z makes x omelette in 30 mins then in 1 min = x/30 combined they make 11 omelette in 10 mins so in 1 min = 1.1 We know 1.1 = 2x/50+x/30 = 110x/1500. Cancelling out the constants gives us x = 15. so 2x = 30 a...
