How many milliliters of curry powder are needed?

Total Curry powder = 1/2 teaspoons hot curry powder + 1/2 teaspoons mild curry powder

Remember that 1 Imperial teaspoon = 5.919ml so for an approximate result, multiply the volume value by 5,919, so:

Total Curry Powder = 2.9597ml + 2.9597 ml = 5.919ml

How many milliliters of chutney are needed?

1 tablespoon of chutney is equal to 17.7582ml

How many litres of water are needed?

1.5 cups water

1 cup = 250 ml

Therefore 1.5cups x 250ml = 375ml

How many potatoes are in 10 kg bag?

5 large potatoes in 1 kg

Therefore there are 50 potatoes in a 10kg bag.

Show by calculations that the recipe can be made 25 times with a 10 kg bag of potatoes?

10kg contains 50 potatoes

The recipe needs 2 potatoes so $n$ is the number of recipes.

$2 \times n =50$

so $n=25$
