Question

The kettle in Keith’s kitchen is 80% full. After 20% of the water in it has been poured out, there are 1152ml of water left. What volume of water does Keith’s kitchen kettle hold when it is full?

Answer 1

Answer:

1800 ml

Step-by-step explanation:

Let kettle can hold 'x' ml of water(when full).

 But here it is just 80% filled.  It means

⇒ volume of water(at 80%) = 80% * x

                           = (80/100) * x

                           = (4x/5)

Now, 20% of the water has been poured out,  that means 100% - 20% = 80 % of the initial amount of water is still in the kettle.

  Remaining water(in ketttle) = 80% of initial volume

                           = 80% of (4x/5)

                           = (16x/25)

Given,  there is 1152 ml of water left.

    ∴ 16x/25 = 1152

       x = (1152 * 25)/16

       x = 1800

Volume of water that Keith’s kitchen kettle hold when it's full is 1800 ml

Answer 2

Answer:

$\large \dag$ Question :-

The kettle in keith's kitchen is 80%full .After 20% of the water in it has been poured out ,there are 1152 ml of water left .What volume of water does Keith's kitchen kettle hold when it is full.

$\large \dag$ Answer :-

According to the given question, we get the answer is The volume of water does the Keith's kitchens kettle hold when it is full is 1800ml.

$\large \dag$ Provided that :-

The Kettle in Keith's kitchens is 80%full .After 20% of the water in it has been poured out,there are 1152ml of water left.

According to the given question, we are going to find,

• What is the volume of water does Keith's kitchens kettle hold when it is full ?

Consider ,

kettle can hold 'x' ml of water when it is full.

• But in the question given,just the 80%is filled .

Therefore,

The volume of water (for 80%)=80%×x

The volume of water (For 80%)=80/100×(x)

We get,

• The volume of water (for 80%)= 4x/3.

And also in the question given that,

• After 20% of the water in it has been poured out .

This means ,

100% - 20% = 80%. ( Of the initial amount of water is still in the kettle )

Then,

• Remaining water =80% of the initial amount of water.

• Remaining water =80 of (4x/5.)
• Remaining water =16x/25.

And ,

Also in the question given that,

• 1152ml of water has been left .

Therefore,

• 16x/25 =1152

• x=1152×25/16

• x =1800ml

$\large \dag$ Hence ,

• This is the perfect answer to your question..
