Answer:
Total weights for the orange and pineapple = 145 + 1015 = 1160 grams.
Step-by-step explanation:
Let the weight of pineapple be x grams and weight of orange by y grams.
Now, weight of a pineapple = 7 (weight of an orange)
∴ x = 7y
Also, x = y + 870 (∵ pineapple weighs 870 more than pineapple)
Substituting the value of x in above equation,
7y = y + 870
7y - y = 870
6y = 870
y = 870/6 = 145
Weight of an orange = 145 grams
Weight of pineapple = 7 × 145 = 1015 grams
Total weights for the orange and pineapple = 145 + 1015 = 1160 grams.
