Problem Solving (PS) | Re: Victor's job requires him to complete a series of identical

total number of days worked=144
total jobs done = 36
average number of days for one job to be done = 144/36=4

let n be nonsuprevised day, and s be suprvd day

day distribution is 72, 72 (half days suprvsd, half days not)

(n+s)/2= 4
n+s =8

from question stmnt we know that, n-s=3
n+s=8
n-s=3
n~= 6
s=3

so to finish 10 jobs:
n*10=6 * 10= 60 days

ans is 60

kudos if u find it helpful.
