Question

Two pipes together can fill a tank in 6 minutes . if one pipe takes 5 minutes more than other find time taken by each pipe separately

Answer 1

Let two pipes be x and y then

=>x+y=6-------------¡]

let x takes 5 minute more than y then

=>x+5=y

=>x-y=-5----------------¡¡]

from both equation we have:

x+y=6

x-y=-5
______
2x=1

x=1/2=0.5m

put the value if x in eq 2)

y=1/2+5

y=11/2=5.5

hence , it takes 0.5 and 5.5 minutes
