Question

The Ratio of Milk and Water in 55 litre of Aduiterates Mik is 7: 4. How much
water must be added to make the mixture Ratio 7: 6 ​

Answer 1

Answer-

In the mixture of 55 litres, let 7x part contains milk and 4x part contains water.

By the question, the mixture contains two types of solution

Therefore,

Total amount of mixture=Mixture of milk+Mixture of water

55 = 7x + 4x

=>55 = 11x

=>x = 5

Putting the value of x in 7x and 4x, we get

7×5 = 35 , 4×5 = 20

Therefore, the ratio is 35/20 = 7/4 = 7 : 4

Now, y should be added to both the mixture to get a ratio of 7 : 6

( 7 + y ) : ( 4 + y ) = 7 : 6

=> 7( 7 + y ) = 6( 4 + y )

=> 49 + 7y = 24 + 6y

=> 7y - 6y = 24 - 49

=> y = - 25

As negative value is not valid, therefore the value of y = 25

Therefore, 25 litres should be added to each of the mixtures to get a ratio of 7 : 6
