Answer: Mavericks, by 5 days
Step-by-step explanation:
let mavericks team efficiency is x and marauders team efficiency is y.
as 4 members of team Maverick and 6 members of team Marauders can finish a job in 10 days. members of Maverick and 7 members of Marauders can finish the same job in 12 days
so (4x + 6y) *1 0 = (3x+7y)*12
x = 6y
it is clear that mavericks efficiency is greater. so
mavericks whole team complete work in
(4x + 6y) *1 0 = 10x*d
4x+x=xd
5 =d
so mavericks will independently complete work in s days.

when you want to use
-printf() scanf()
-log() abs() pow()
-clrscr() getch() terminate()
and your program restrictions are such that you have to use only 1 header file
Is it Possible......if yes which header file will you use....
How you will do it? A can finish a job alone in 42 days and C can do the same in 35 days. A and B both work on the project for 5 days, after which B leaves for vacation. A works for a day alone, after which C joins him and they both work together on the project for 8 days, after which A leaves for vacation. C works on the project alone for a day, after which B returns and both B and C together finish the project in 5 days. How long will it take for B to finish the project alone?
a. 35 days
b. 42 days
c. 37.5 days
d. 44 days
