Question

Milk and Water are in the ratio 5:3 in 400 ltrs of a mixture. how much of water should be added to make the ratio 5:4

Answer 1

Answer:

250 ltrs

Step-by-step explanation:

Let the Milk and Water be 5x and 3x, then

5x + 3x = 400

8x = 400

x = 400 / 8

x = 50

Milk = 50 × 5 = 250

Water = 50 × 3 = 150

Now,

(250+x) / (150 + x) = 5 / 4

1000 + 4x = 750 + 5x

x = 250

So, the ratio of Milk and Water

250 + x : 150 + x = 5:4

250 + 250 : 150 + 250 = 500 : 400

= 5:4

DONE;
