Question

a water tank in a school contain 12000 litre of water each student drink 4 litre of water in a day there are 650 students in in the the school how much water is left in the water tank at the end of the day​

Answer 1

Answer:

20 liters

(4/5 x) - 8 liters = 2/3 x

Solving for x, x=60 liters

X is the total number of liters the container holds.. This is not what the question asked, but it makes it possible to calculate the answer.

Now we can find the number of liters we started with. 4/5 of 60 is 48 liters. Then we took 8 liters away. Now we have 40 liters.

40 liters + y = 60 liters. In this equation we solve for y. y = 20. We would need to add 20 liters to fill up the container.

Answer 2

Answer:

which student drink water 4 litre

student 650

then 650 ×4= 2600

total water 12000

now 12000 - 2600= 9400 litre water left
