Answer:the secretary spends 15.71 % of her time

,
• Filing letters = ,1/7 * 35 h, = 5 hours
,
• Typing = ,1/2 *35 , = 17.5 hours
(i) Total time spent on office work = (7 + 5 +17.5 )hours = 29.5
(ii) Total hours - total time spent = time she acted as a receptionist
35 hour - 29.5 hours = 5.5 hours
This means that the secretary spends 5.5 hours acting as a receptionist
(iii) CONVERT 5.5 HOURS INTO PERCENTAGE :
This means that the secretary spends 15.71 % of her time acting as a receptionist
