Question 20 - Upper Level: Mathematics Achievement Practice Test for the ISEE

Simone keeps a monthly record of the average weight of her chickens. For the month, her four chickens weighed 2.4 kg, 2.2 kg, 1.9 kg and 1.7 kg. However, her weighing scale has a 100-gram limit of reading. She wants the figures to be conservative and decides to use the lower bounds of the measured weights.

What is the result of Simone’s computation for the average weight of the chickens?
