X = 32

Y = 96

Explanation:

Z = 5%

Z = (0.04X + 0.08Y) / (X + Y)

we can substitute Z:

0.05 = (0.04X + 0.08Y) / (X + Y)

0.05 (X + Y) = 0.04X + 0.08Y

0.05X + 0.05Y = 0.04X + 0.08Y

0.01X = 0.03Y

X = 0.03Y / 0.01 = 3Y

This means that we must choose one value for Y that divided by 3 equals another option:

the only possibility that fits the equation is:

X = 32 Y = 96
