7 taps of the same size fill a tank in 1 hour 36 minutes. How long will 8 taps of the same size take to fill the tank?
More the number of taps, lesser the time required to fill a tank. So, it is an inverse proportion.
Let the required time be x minutes.
⇒ 7 × (60 + 36) = 8 × x
⇒ x = = 84 minutes = 1 hour 24 minutes
