Answer 2

Answer:

The time taken by 5 taps to empty the tank is 20 minutes

Step-by-step explanation:

Given as :

The time taken by 9 taps to empty the tank = 36 minutes

Let The time taken by 5 taps to empty the tank = t minutes

According to question

Applying unitary method

∵ The time taken by 9 taps to empty the tank = 36 minutes

So, The time taken by 1 tap to empty the tank = $\dfrac{36}{9}$ minutes

∴ The time taken by 5 taps to empty the tank =  $\dfrac{36}{9}$  × 5 minutes

i.e t = $\dfrac{36}{9}$  × 5 minutes

Or, t = 4 × 5 minutes

∴   t = 20 minutes

So, The time taken by 5 taps to empty the tank = t = 20 minutes

Hence, The time taken by 5 taps to empty the tank is 20 minutes . Answer
