a pineapple is 7 times as heavy as an orange. the pineapple also weight 870 grams more than orange what is the total weight in grams for the pineapple and orange

Verified Answer :

let's call p= pineapple weight
and. g=orange weight

we have p=7g
and. p=g+870

replacing the the second equation in the first we have
g+870=7g

that means 870 = 7g - g
870 = 6g
g = 870/6 = 145

and p = 7*g = 1015
