Number of calories in 8 ounces of orange juice = 100

Number of calories in 1 ounce of juice = $\frac{100}{8}$

Number of calories in 4 ounces of juice = $\frac{100}{8}*4=50$ calories

Number of calories in 8 ounces of pineapple juice = 140

Number of calories in 1 ounce of juice = $\frac{140}{8}$

Number of calories in 4 ounces of pineapple juice =

$\frac{140}{8}*4=70$ calories

Now the mixture has 50+70 = 120 calories in 8 ounce.

So, 1 ounce of mixture has = $\frac{120}{8}= 15$ calories.
