Question

The volume of three containers is same
The ratios of milk to waterin the three contain
ers are 3:2, 73 and 11:4 respectively. If the
content of the three containers is mixed to
gether what will be the new ratio of milk to
water?​

Answer 1

Answer:

The ratio of milk to water in three containers of equal capacity is 3 : 2, 7 : 3 and 11 : 4 respectively. The three containers are mixed together. What is the ratio of milk to water after mixing?

How to add notes and navigation metadata directly in source code.

Let the capacity of each container be x.

Now, in first container there are 3 parts of milk and 2 parts of water. Mathematically it can be written as:

3/5x milk and 2/5x water.

Similarly, second container has 7/10x milk and 3/10x water.

And, third container has 11/15x milk and 4/15x water.

Now, after mixing:

Total milk = (3/5+7/10+11/15)x = 61/30x

Total water = (2/5+3/10+4/15)x = 29/30x

So, milk to water ratio is (61/30x)/(29/30x)

So, milk to water ratio is 61/29.

Answer 2

Answer:

Let the quantity of mixture in each container be x. Then, 

Sulphuric acid in 1 st container =53x Water in 1 st container =52x

Sulphuric acid in 2 nd container =107x Water is 2nd container =103x 

Sulphuric acid in 3rd container =1511x

Water in 3rd container =154x∴ Required ratio =(53x+107x+1511x):(52x+103x+154x)=(6036+42+44):(6024+18+16)=122:58=61:29.
