Question

6. For every 8L of milk, one litre of water is added by
a milkman. What is the per cent of water added by
him?​

Answer 1

Step-by-step explanation:

Pure milk in the mixture = 8 L

Water in the mixture = 1L

Total volume of mixture = 8 + 1 = 9L

Percentage of water =

Vol. of water / Vol. of mixture × 100

Percentage of water = 1/9 × 100

= (11whole 1/9 )%
