1. 20
2. 40
3. 10
4. 70

Answer 1

Correct Answer - Option 3 : 10

Given∶

Number of taps = 8

Time = 80

Formula used∶

M₁ T₁ = M₂ T₂

Where M and T represents number of taps and time.

Calculation∶

8 × 80 = M₂ × 64

⇒ M₂ = (8 × 80)/64

⇒ M₂ = 10

∴ 10 taps are required to fill a container in 64 minutes.
