Shezad needs 10 litres of lemon squash to fill 20 cups. How much squash will he need to fill 25 cups?

(25/20) * 10

To find out how much squash Shezad will need to fill 25 cups, we can set up a proportion based on the information given.

Let's assume that the amount of squash required is "x" liters.

According to the problem, 10 liters of squash are needed to fill 20 cups.

So, the ratio of squash to cups is 10 liters / 20 cups.

We can set up the proportion as follows:

10 liters / 20 cups = x liters / 25 cups

To solve for x, we can cross-multiply and then divide:

20 * x = 10 * 25

20x = 250

Dividing both sides by 20:

x = 250 / 20

x = 12.5

Therefore, to fill 25 cups, Shezad will need approximately 12.5 liters of squash.

To find out how much squash Shezad will need to fill 25 cups, we can use a proportion.

Let's set up the proportion:

10 litres / 20 cups = x litres / 25 cups.

To solve for x, we can cross-multiply and then divide:

10 litres * 25 cups = 20 cups * x litres.

250 litres = 20x.

Divide both sides of the equation by 20:

250 litres / 20 = x.

x = 12.5 litres.

So, Shezad will need 12.5 litres of lemon squash to fill 25 cups.
