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 30% 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% - 30%
= 70%
100% → 50
1% → 50 ÷ 100 = 0.5
70% → 70 x 0.5 = 35
Number of foolscaps sold in November = 35
Answer(s): 50; (b) 35
