Question

A can do a work in the same time as B and C together can do that work. If A and B can do this work together in 10 days and C alone can do it in 50 days, then in how much time will B alone be able to do that work?

Answer 1

Step-by-step explanation:

A=(b+c)

ATQ:

A+b =10------( 1 )

c=50

A+(A-C)=10

A^2-AC=10

A^2-A= 10÷50

A^2-A =1÷5
