Question

4 groups of backpackers picked blueberries over a two hour period.

The weight of the blueberries collected (in kg) by the groups in each hour is shown in the table below.


Group 1 Group 2 Group 3 Group 4
1st hour 2.57 2.89 2.5 2.87
2nd hour 2.35 2.06 2.92 2.53

Which group picked the greatest mass over the two hours?

Worked Solution

A possible strategy:

A quick estimate of the 1st 2 groups shows that both sums will be lower than 5 kg.

⇒\rArr Evaluate only Group 3 and 4

Group 3: 2.5 + 2.92 = 5.42 kg

Group 4: 2.87 + 2.53 = 5.40 kg

∴\therefore {{{correctAnswer}}} picked the greatest mass.
