Question

.

Parcel A is heavier than parcel B by
2.5 kg. Parcel C is lighter than parcel
B by 4.86 kg. How heavy is parcel A if
parcel C is 6.2 kg?

Answer 1

Answer: 13.56 kg

Explanation:

We can make two equations:

1) A = B + 2.5

2) C = B - 4.86

Replace C with 6.2.

(6.2) = B - 4.86 can be rewritten as 6.2 + 4.86 = B.

B = 11.06

Add 2.5 to 11.06 and you get 13.56 kg.
