Present the following information in suitable tabular form: (i) In 2015, out of total 2000 workers in a factory, 1550 were members of a trede union. The number of women workers emplouees was 250, out of which 200 did not belong to any trade union. (ii) In 2018, the number of union workers ws 1725 of which 1600 were men.

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’.

Represent the following complex numbers in the complex plane: (i) 1+2i (ii) 5+7i (iii) 0+0i (iv) i .
