If the punch is 2 parts pineapple to 3 parts apple,
the pineapple is 2%2F5 of the punch and
the apple is 3%2F5 of the punch
In 1 cup, pineapple is 2%2F5 cup
apple is 3%2F5 cup
140 calories/cup x 2%2F5 cup = 56 calories
120 calories/cup x 3%2F5 cup = 72 calories
In a cup of punch, there are 56+%2B+72+=+128 calories
