Given below are two quantities named I and II. Based on the given information, you have to determine the relation between the two quantities. You should use the given data and your knowledge of Mathematics to choose among the possible answers. Quantity I: There are 42 workers in a factory with an average weight of 65 kg. The ratio of the number of male workers to female workers is 13: 8. If the average weight of male workers and female workers is 72 kg and ‘x’ kg respectively, then find the value of ‘x’. Quantity II: The average weight of a class of 25 students is ‘x’ kg. If a student whose weight is 100 kg is excluded, then the average of the class reduces by 2 kg. Find the value of ‘x’.

In a class with a certain number of students, if one student weighing 50 kg is added then the average weight of the class increases by 1 kg. If one more student weighing 50 kg is added, then the average weight of the class increases by 1.5 kg over the original average. What is the original average weight (in kg) of the class? (a) 2 (b) 4 (c) 46 (d) 47
