Question

If beans are costing K500 per kg and maize is costing K600 per kg in what ratio should the two commodities be mixed to cost K525per kg?

Answer 1

Step-by-step explanation:

Let the quantity of maize and beans be x and y respectively.

Then we know that

$x + y = 1 \\ 500x + 600y = 525 \\ 500 - 500y + 600y = 525 \\ 100y = 25 \\ y = 0.25kg \\ and \: x = 0.75kg$

Hence ratio is 3:1

Answer 2

Answer:

bean costing =x =K500 per kg

maize costing = y =K600 per kg

and ,

1/2kg of x +y = K525

x=K500 =225

y=K600/2 =300

x+y = 300 +225 =525
