As per the formula of alligation for cheaper and dearer materieals,

Here, d or the dearer material is Liquid 1 as one litre of liquid 1 weighs 1000 grams, and c or the cheaper liquid is liquid 2 because one litre of liquid 2 weighs only 800 gm.

Mean for 1 L mixture = 480 x 2 = 960.

Puttig values in the formula, we get

So, L1 is 4 units out of total 5 units. Hence %L1 = 4/5 * 100 = 80%.
