(8 marks)

1. Determine the standard time for the following job, add 20% for allowance. The times shown in Table-2 are continuous stopwatch readings in hundredths of a minute. Performance rating factor for elements 1, 2 and 3 are 120%, 110% and 95% respectively.

Table-2 Continuous Stop Watch readings of the job

No	Element	Cycle
		1	2	3	4	5	6
1	Put glycerine on thumb, forefinger and middle fingers of both the hands. (for counting sheets)	05	-	63	-	117	-
2	Take out 4 sheets each with each hand from piles of sheets placed on either side of the operator.	20	46	77	101	150*	176
3	Staple 8 sheets together and put them in a tray.	30	57	87	112	161	186

* the operator dropped 4 sheets on the floor and then picked up

and stapled them with another 4 sheets.
