Answer:
4 hours
Step-by-step explanation:
A= 12 hours , A will fill 1/12 of tank in an hour
B= 15 hours , B will fill 1/15 of tank in an hour
C= 10 hours , C will fill 1/10 of tank in an hour
No. of hours it will take to fill tank
= 1 ÷ (1/12 + 1/15 + 1/10)
= 1 ÷ 15/60
= 60/15
= 4
Therefore, it will take 4hours to fill up the tank
