HIGH RATED GABRU---HARSH ♦️♦️♦️♦️♦️♦️♦️♦️♦️♦️let’s say that :
a is the quantity per day that A produces.
b is the quantity per day that B produces
c is the quantity per day that C produces
W is the total quantity required to finish the job
then we know that :
a = b + c
10a + 10b = W
15c = W
we can rewrite this as :
10a + 10b = 15c
or:
2a + 2b = 3c
2(b + c) +2b = 3c
2b + 2c +2b = 3c
4b + 2c = 3c
4b = 3c - 2c
4b = c
meaning, 1 day of work by C equals 4 days of work by B
in other words, C is 4 times as productive as B
therefore, if C needs 15 days to finish the job, B will need 60 days to finish the same job.
The question was not asked, but A needs only 12 days to finish the job.
perhaps you can work this one out yourself.
All the best !
