6. The human resources/personnel manager of a firm submits the following report on labour and staff to the managing director:

"The total number of employees is 136, of whom 62 are male. Of these men, 43 are industrial laborers and the rest are staff. The age distribution of the 43 is \'under 18\' (seven), \'18–45\' (22) and the others are over 45. Our total industrial labour force is 113, of whom 25 are\'under 18\' and 19 are \'over 45\'. The total number of under-18\' on the site is 29 (10 male, 19 female). There are 23 \\\\\\\'over-45s\', of whom only 4 are male staff."

The managing director, quite rightly, thinks that this is gibberish and instructs you to present it to him in a tabular form which he can readily understand. Show the table you would produce. (20)
