If it fills 30 galons per minute, that means that it fills 30*60 minutes = 1800 gallons per hour.

We know that 1 gallon = 3,79 liters, so 1800 gallons per hour = 1800 * 3,79 liters = 6822 liters per hour.

in an examination ,80%examines passed in English ,70%in mathematics and 60% in both subject if 45 examines failed in both find t
stiv31 [10]

Answer:

135 and 135

Step-by-step explanation:

The computation is shown below:

The number of examiners who passed in only one subject is as follows

=  n(E) - n(E ∩M) + n(M) - n(E ∩M)

= (80 - 60 + 70 - 60)%

= 30%

Now the number of students who passed in minimum one subject is

n(E∪M) = n(E) + n(M) -  n(E ∩M)

= 80 - + 70 - 60

= 90%

Now the number of students who failed in both subjects is

= 100 - 90%

= 10% of total students

= 45

So total number of students appeared for this 450

So, those who passed only one subject is

= 450 × 30%

= 135

Now the Number of students who failed in mathematics is

= 100% - Passed in Mathematics

= 100% - 70%

= 30% of 450

= 135
