Given:

The ratio of oil and water in the mixture=7:8

The total quantity of the mixture=30 litres

To find:

The new ratio of oil and water

Solution:

The new ratio of oil and water is 1:1.

We can find the ratio by following the given steps-

We know that the total quantity of the mixture is 30 litres.

The ratio of oil and water in this mixture is 7:8.

So, we will calculate the quantity of oil and water in the mixture.

The amount of oil in the mixture=7/15 of the total quantity of the mixture

=7/15×30

=7×2

=14 litres

The amount of water in the mixture=8/15 of the total quantity of the mixture

=8/15×30

=8×2

=16 litres

Now, we know that 2 litres of oil have been added o the mixture.

So, the new amount of oil in the mixture=Original amount+2

=14+2

=16 litres

So, the new ratio of oil and water=New amount of oil: Amount of water

On putting the values,

The new ratio=16:16

=1:1

Therefore, the new ratio of oil and water is 1:1.
