Question 33

A smaller parcel and a larger parcel have masses in the ratio 2:3. The larger parcel is 54 kg. What is their total mass?

  1. 72 kg from adding the two known terms
  2. 90 kgBonne réponse
  3. 81 kg from scaling the larger share
  4. 56 kg from adding the smaller ratio term

Explication

Three parts correspond to 54 kg, so each part is 18 kg; all 5 parts therefore weigh 90 kg. Adding 2 kg to 54 kg would confuse the smaller ratio term with the smaller parcel's actual mass.
