Given : Ram works 20 hours in a week (monday to friday)last week he worked 13/2 hours on Monday 3 hours on Tuesday 15/4hrs on Wednesday and 5/2 hours on Thursday
To Find : how many hours did he work on Friday?
Solution:
Work on Mon + Tue + Wed + Thur + Fri = Total Work
=> 13/2 + 3 + 15/4 + 5/2 + Fri = 20
=> (26 + 12 + 15 + 10)/4 + Fri = 20
=> (63/4) + Fri = 20
=> Fri = 20 - 63/4
=> Fri = (80 - 63)/4
=> Fri = 17/4
17/4 hours he worked on Friday
