$8$

Hint 1

For $100$ pancakes we need -

$25$ eggs

$4$ Litres milk

$5 kg$ flour

$1 kg$ butter.

Now calculate for one pancake how much ingredient is needed?

Hint 2

For one pancake we need,

$0.25$ egg

$0.04$ Litres milk

$0.05 kg$ flour

$0.01 kg$ butter.

Calculate how many pancakes can be made with each ingredients available.

Hint 3

With $6$ eggs we can have $24$ pancakes.

With $400 g$ flour we can have $8$ pancakes.

With $0.5 $ Litres milk we can have $12.5$ pancakes.

With $200 g$ butter we can have $20$ pancakes.

Compare the number of pancakes for each ingredient to make the pancake complete.

Hint 4

So, we can have $8$ pancakes complete.
