Answer 2

Answer:

option 2 -- 5000 litres

Step-by-step explanation:

Time to empty the tank

A = 15 hrs

B= 12 hrs

Capacity = 60 Units

Efficiency:

A= -4

B=-5

According to the problem, After 7 hours,750 litres filled in the tank

3B+(A+B)4=60 Units

(-5)*3 + (-4-5)*4 = 60

-51 = 60

9 units = 750 litres

total capacity X= 60 Units = 5000 litres
