The average mass of 2 durians and 3 apples is 1.85kg. The average mass of 3 durians and 3 apples is 1.92kg. What is the mass of 1 durian?

Answer 1

Using the definition of "average", and A and D for the masses of each,

2D + 3A = 1.85 x 5 = 9.25
3D + 3A = 1.92 x 6 = 11.52

D = 2.27 kg

This leads to a very high mass for 1 apple-- over 1 kg. The numbers seem raqther phoney

Answer 2

yup, it is...thanks
