Question

The ratio of milk and water in 66 kg of adulterated
milk is 5:1. Water is added to it to make the ratio 5: 8.
The quantity of water added is​

Answer 1

Answer:

77 kg

Step-by-step explanation:

Let the milk and water of adulterated milk be 5x and x

So ATP,

5x + x = 66 kg

6x = 66 kg

x = 11kg

Then milk and water of it are 55kg(5 * 11kg) and 11 kg(1 * 11kg) respectively

Let the measure of milk added to it to make it in ratio 5:8 or 5/8 be x kg

ATP,

55 / 11+ x = 5/8

440 = 55 + 5x (cross multiplication)

5x = 440-55 = 385

x = 385/5 = 77 kg

77 kg of water should be added to adulterated milk to make it 5:8
