Question

The minimum quantity of milk in litres (in whole number) that should be mixed in a mixture of 60
litres in which the initial ratio of milk to water is 1 : 4 so that the resulting mixture has 15% milk
is
(b) 4
(a) 3
(C) 5
(d) This is not possible​

Answer 1

Answer:

Total mixture = 60L

Milk: Water = 1: 4

Milk = 1/5 x 100 => 20%

and after adding only milk, the quantity of milk is becoming 15% which is not technically correct.

Because after adding a particular fluid, that's quantity should get increased.

Step-by-step explanation:

Answer 2

Concept:

The ratio is the comparison between quantities of two items.

Given:

Total mixture = 60 litres

The ratio of initial milk to water = 1:4

Resulting mixture = 15%

Find:

We have to find the amount of milk.

Solution:

The total amount of mixture = 60 liters

The ratio of milk and water = 1:4

Milk = 1/5 x 100

Milk =  20%

And after adding only milk, the quantity of milk is becoming 15% which is not technically correct.

Because after adding a particular fluid, that quantity should get increased.

Hence, the correct option is (d) This is not possible.
