The following table shows the weight data of langurs in an animal facility. Without doing any computations, can you tell whether there are more male langurs or more female langurs? Or are they equal in number? (i) Which of the following expression(s) describes the given scenario? (a) (16.5x + 13.8y) / (x + y) = 14.925 (b) (16.5x + 13.8y) / 60 = 14.925 (c) (16.5x + 13.8y) / 2 = 14.925 (d) (16.5x + 13.8y) / (16.5 + 13.8) = 14.925 (ii) Find out how many male langurs are present. (iii) A female langur weighing 15.2 kg is admitted to the facility. What is the average weight of the female langurs after this? (iv) Two male langurs weighing 16.9 kg and 16.1 kg are released from the facility. What is the average weight of the male langurs after this? (v) Now, suppose one of the male langurs lost 1 kg of weight. What is the average weight of all the male langurs after this?
