25PT and 75 FT
lets say work time of FT 10
wotk time of PT=10*3/5=6
total work hours for FT=750
total work hours for PT=150
wage per hour is same so the ration of total wages is 150/750=1/5
oops sorry, its asking for the ratio to total i.e. 150/(150+750)=1/6

Should be - C
Let number of employees be - 100
Number of hours = x
wages per hour = y
total Part time wages = 25 * 3/5 x * y = 15xy
total wages of all member = 15xy + 75xy
Ratio - 15xy / 90xy = 1/6
