You can put this solution on YOUR website! With a fixed amount of money $M, Mrs. Ushna Tehseen can use it to pay the wages of a local worker for 40 days or to pay the wages of an unskilled foreign worker for 60 days. If she employs one local worker and one unskilled worker foreign worker for a top secret project, how many days will the $M be enough to pay for these two workers?
...
local worker gets M/40 per day
Foreign worker gets M/60 per day
Total per day if both are employed = M/40 + M/60
(3M+2M)/120 for 1 day.
=5M/120 for 1 day
Total money $ M
wages /day = 5M/120
...
Number of days = total money / wages per day
M/ (5M/120)
M*120/5M
120/5
24 days.
