Answer 2

Answer:

Given

Step-by-step explanation:

Time taken by tap A =8 hrs

Time taken by tap B=12 hrs

Part of water filled by tap A in 1 hour=1/8

Part of water filled by tap B in 1 hour=1/12

Part of water filled by both the taps in 1 hour=1/8 + 1/12

3/24 + 2/24

5/24

Time taken by both taps to fill the utensil=24/5 hrs or 5 4/5
