Problem Solving

There are 2 kinds of staff members in a certain company, PART TIME AND FULL TIME. 25 percent of the total members are PART TIME members others are FULL TIME members. The work time of part time members is 3/5 of the full time members. Wage per hour is same. What is the ratio of total wage of part time members to total wage of all members?

A.1/4
B.1/5
C 1/6
D 1/7
E 1/8

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

Cool solution frnds..u rock!!

OA is C
