Best answer
Correct Answer - Option 2 : 24 

Given

Number of taps = 8

Time taken by 8 taps to fill the vessel = 72 minutes

Formula used

If Tapis a number of taps fills a vessel in Timeand Tapis a number of taps fills a vessel in Time2, then

Tap× Time = Tap × Time2

Calculation

Let x taps fills the same vessel in 24 minutes.

Tap= 8, Time 1 = 72 minutes

Tap= x, Time2 = 24 minutes

⇒ 8 × 72 = x × 24

⇒ (8 × 72)/24 = x

⇒ 24 taps = x

∴ 24 taps fills the large vessel in 24 minutes
