Write your answers in the spaces provided. 1 Mrs Tan went to buy some durians. She noticed the seller weighed each durian individually and added the masses of the durians together to obtain the total mass. Fig. 1.1 (a) The scale shown in Fig. 1.1 was used to weigh a durian. Record the mass of the durian that is shown on the scale to the correct precision in kg. mass of durian = ……………………………. [ 1] (b) Mrs Tan bought 4 durians. When she weighed them altogether at home, the scale showed a mass that was 100 g less than what she was charged for . State if Mrs Tan’s method of weighing the durians will give a more accurate mass than the seller’s method. Explain the reasoning behind your answer. Assume that both scales have the same precision and accuracy. …………………………………………………………………………………………..… ………………………………………………………………………………………. ….
