PSLE Look at the graph and answer the following questions.
- How many foolscaps did the shop sell in August?
- The number of foolscaps sold in November was an 50% decrease from the number sold in October. How many foolscaps were sold in November?
(a)
Number of foolscaps sold in August = 40
(b)
Total number of foolscaps sold in November as compared to October
= 100% - 50%
= 50%
100% → 10
1% → 10 ÷ 100 = 0.1
50% → 50 x 0.1 = 5
Number of foolscaps sold in November = 5
Answer(s): 40; (b) 5
