Answer:24/5 hrs or 5 4/5 hrs
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
