Question

दूध और पानी के 72.9 लीटर मिश्रण में दूध और पानी का अनुपात 7:2है। दूध और पानी की पृथक-पृथक पाना झात कीजिए। The ratio of milk and water is 7:2 in 72.9 litre of a mixture. Find the separate quantity of milk and water
​

Answer 1

Step-by-step explanation:

72.9/9=8100

8100*2=16200

8100*7=56700

Answer 2

The quantity of milk is 56.7 litres.

The quantity of water is 16.2  litres.

-------------------------------------------------------------------------------------

Let's solve the given problem:

The total quantity of the mixture (milk + water) = 72.9 litres

The ratio of milk and water in the mixture = 7 : 2

So, let's say,

"7x" → Quantity of milk

"2x" → Quantity of water

We can form an equation as,

[Qty. of milk] + [Qty. of water] = Total mixture

$\implies 7x + 2x = 72.9$

$\implies 9x = 72.9$

$\implies x = \frac{72.9}{9}$

$\implies \bold{x =8.1}$

Therefore,

The quantity of milk in the mixture = $7x = 7\times 8.1 = \bold{56.7\:litres}$

and

The quantity of water in the mixture = $2x = 2\times 8.1 = \bold{16.2\:litres}$

Thus, the separate quantity of milk and water is 56.7 litres and 16.2 litres respectively.
