A basket with 12 apples has a mass of 3105 grams. The same basket with 7 apples has a mass of 1980 grams. Each apple has the same mass. What is the mass of the basket?

Answer 1

(3105-1980)/(12-7) = 225 grams/apple

3105 - (12*225) = 405 grams = Wt. of the basket.

1980 - (7*225) = 405 grams = Wt. of basket.

Note: After removing 7 apples, we took
the remaining wt(1125grams) and divided
by the remaining # of apples(5). That gave us the Wt. per apple.

Answer 2

Correction:
After removing 5 apples, we took the
reduction in Wt.(1125grams) and divided
by the # of apples removed(5). That gave us the wt. per apple.

Answer 3

A different Method:

X Grams per apple.
Y Grams = Wt. of basket.

Eq1: 12x + Y = 3105
Eq2: 7x + Y = 1980
Diff: 5x = 1125
X = 225

In Eq1, replace X with 225:
12*225 + Y = 3105
Y = 3105 - 2700 = 405.
