Marks: +1, -0

Two vessels contain equal quantity of mixtures of milk and water in the ratio 5:2 and 6:1 respectively. Both the mixtures are now mixed thoroughly. Find the ratio of milk to water in the new mixture so obtained.

$3:11$
$11:3$
$12:13$
None

Solution:

Concept:

Assume each vessel contains equal total quantity, then add the milk and water parts separately.

Explanation:

Let the quantity in each vessel be

7

units (common sum of the ratios).

First vessel (

5:2

): Milk =

5

units, Water =

2

units.

Second vessel (

6:1

): Milk =

6

units, Water =

1

unit.

After mixing, total Milk =

5+6=11

units, total Water =

2+1=3

units.

Thus, milk to water ratio =

11:3

.

Answer:

11:3
