coffee costing $250 per kg was mixed with chicory costing $75per kg in th ration 5:2 for a certain blend. if the mixture was sold at $230 per kg,find the gain or loss percent.

I sure hope these are not US or Canadian dollars.

number of kg of expensive : cheaper = 5x : 2x

cost = 250(5x) + 75(2x) = 1400x
selling price = 230(7x) = 1610x

percent gain/loss based on cost price
= (1610x - 1400x)/(1400x)
= 210/1400
= .15

profit is 15%

To find the gain or loss percent, we need to calculate the cost price and the selling price.

Given:
Cost of coffee per kg = $250
Cost of chicory per kg = $75
Ratio of coffee to chicory = 5:2

Let's assume the quantity of coffee as 5x and the quantity of chicory as 2x. This means the total quantity of the mixture is 7x.

Cost of coffee in the mixture = 5x * $250 = $1250x
Cost of chicory in the mixture = 2x * $75 = $150x

The total cost of the mixture is the sum of the cost of coffee and chicory:
Total cost = $1250x + $150x = $1400x

Given that the mixture is sold at $230 per kg, the selling price is $230x.

To find gain or loss percent, we need to calculate the difference between the selling price and the cost price, and then convert it to a percentage:
Gain or Loss percent = ((Selling price - Cost price) / Cost price) * 100

Now, let's calculate the gain or loss percent:
Gain or Loss percent = ((230x - 1400x) / 1400x) * 100
= ((-1170x) / 1400x) * 100
= (-1170 / 1400) * 100
= -83.57

Therefore, the gain or loss percent is approximately -83.57%. This indicates a loss.
