Let the time taken by the faster pipe to fill the cistern is x minutes, then the time taken the slower pipe will be (x+3) minutes.
The portion of cistern filled by the faster pipe in 1 minute is
x
1
.
The portion of cistern filled by the faster pipe in
13
40
minutes is
13x
40
.
The portion of cistern filled by the slower pipe in
13
40
minutes is
13(x+3)
40
.
As the cistern is filled fully in
13
40
minutes, then,
⇒
13x
40
+
13(x+3)
40
=1
⇒
x

+
(x+3)

=
40
13
⇒40(2x+3)=13(x+3)
⇒13x

−41x−120=0
⇒13x

−65x+24x−120=0
⇒(x−5)(13x+24)=0
∴x=5,x=−
13
24
∵ x can not be a negative
Therefore, the faster pipe will fill the cistern in 5 minutes and the slower pipe will fill the cistern in 5+3=8 minutes.
