initial half filled in 3 hrs
for next half:1/time =1/3 +1/3
=2/3 hrs
time for half with 2 taps =3/2hrs
total time =3+3/2
=9/2 hrs
for next half:1/time =1/3 +1/3
=2/3 hrs
time for half with 2 taps =3/2hrs
total time =3+3/2
=9/2 hrs
Sorry to say it's wrong, because, question says two more were introduced, The answer to the question is 4 hrs !
