Question

19. In a mixture of 100 litres of milk and water, 25%
of the mixture is milk. How much water should be
added to the mixture so that milk becomes 20% of
the mixture?
(a) 25 litres
(b) 15 litres
(c) 20 litres
(d) 24 litres​

Answer 1

Answer:

25 litres

Step-by-step explanation:

20% of x = 25 litre

20/100 × x = 25

x = 25 × 100/ 20

x = 5× 25

x = 125 litre

mixture should be 125 litre and 100 litre is present ,so,

water required = 125 -100

= 25 litre
