A, B and C can together do a job in 9 days. C alone can do the job in 36 days. In how many days can A and B do 50% of the job working together?
Answers
Answer:
6 days
Step-by-step explanation:
A+B+C =9 days
c = 36 days
By LCM we find that total work is 36 and (a+b+c) can do 4 work in one day while c can do 1 work
so a+b+c-c = 3
it means a and b can do 3 works in one day
also we know that work is 50 % it means now work is 18
a+b = 18/3= 6
A solution is defined as a:

A solution is a homogeneous mixture of two or more substances. A solution may exist in any phase.
A solution consists of a solute and a solvent.
The solute is the substance that is dissolved in the solvent.
For example, in a saline solution, salt is the solute dissolved in water as the solvent.
