Answer

Answer Details

This question tests reading a linear scale between two labelled graduations, then converting and scaling the reading.

(a) The pointer lies on the unlabelled graduation exactly midway between 60 and 80, giving a reading of \(70\) kg. [1]
(b) Multiplying by 1000 to convert kilograms to grams: \[70 \times 1000 = 70\,000 \text{ g}\] [1]
(c) Multiplying the mass of one sack by the number of sacks: \[70 \times 6 = 420 \text{ kg}\] [1]
