Question

two vessels A and B contain milk and water in the ratio 3:2 and 7:13 respectively .they are mixed in the ratio 2:3 .find the ratio of milk and water in the final mixture.​

Answer 1

3x and 7x unit of milk in A and B

2x and 13 unit water in A and B

ratio is 2:3 or mixing A and B hence multiply A units by 2 and B units by 3 unit and then divide to find ratio

Now in the mixture

2×3x=6x and 3×7x=21x unit of milk is present

2×2x=4x and 3×13x=39x unit of water is present

$\frac{6x + 21x}{4x + 39x} = \frac{27x}{43x} = \frac{27}{43}$
