The Ratio of the given is 3: 1

Solution:

According to the question,

Given Data:

Coffee at Rs. 625 mixed with coffee at Rs.750  

To Find:

Calculate the proportion of coffee

Step-by –Step Explanation:

Step 1:

Let the ratio be x: y (coffee 625 : coffee 750) in (x+y) kg

Step 2:

Then.,

x (625) + y(750) = 675 (x+y)

x ( 675 - 650) = y (750-675)

Step 3:

25x = 75y

Hence....

$\frac{x}{y} = \frac{75}{25} = \frac{3}{1}$

Result:

Therefore x : y = 3 : 1
