no way to tell. How is their pay related to the time worked?
If their hourly pay rate is the same, then it appears that P worked 3/4 as long as Q.
So if P can do the job in 20 days, Q can do it in 80/3 days.
1/20 + 1/(80/3) = 7/80
So they can do the job in 80/7 days together
P and Q completed a work together and were paid rs 1,080 and rs. 1,440, respectively. If P can do the entire work in 20 days, how many days did they take to complete the work together?

How 3/4 came??
Kindly explain @oobleck
Kindly explain @oobleck
he got paid 3/4 as much, so ...
Sorry dear, @ oobleck, i didn't understand 3/4 concept
Efficiency=Money paid
P/Q = 1080/1440=3/4
Total work = 3*20=60
(As efficiency of P is 3 and can do the work in 20days)
P+Q will do the work in 60/3+4=60/7= 8 4/7 days.
P/Q = 1080/1440=3/4
Total work = 3*20=60
(As efficiency of P is 3 and can do the work in 20days)
P+Q will do the work in 60/3+4=60/7= 8 4/7 days.
