Question

A and B together can do a work in 72 minutes but b takes 1 hour more than a takes to do the workeach work alone find the time taken by A and B each working alone to do the same work ​

Answer 1

Answer:

let A takes x hr to finish the work alone

so B takes x+1 hr

now,1/x + 1/(x+1) = 1/1.2

=>after solving the eqn

we get x=2 and -3/5(can't be)

hence A will take 2 hr and B will take 3 hr

let A complete the work in X hrs 

so 1hr work of A =1/X

1hr work of B=1/1=X

1hr work of (A+B)= 1/1=X + 1/X = 1/1.2

SOLVING FOR X WE HAVE X= (6,-4)

so A completes in 6 hrs and B in 7 hrs
