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 20% decrease from the number sold in October. How many foolscaps were sold in November?
(a)
Number of foolscaps sold in August = 50
(b)
Total number of foolscaps sold in November as compared to October
= 100% - 20%
= 80%
100% → 30
1% → 30 ÷ 100 = 0.3
80% → 80 x 0.3 = 24
Number of foolscaps sold in November = 24
Answer(s): 50; (b) 24
