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 10% decrease from the number sold in October. How many foolscaps were sold in November?
(a)
Number of foolscaps sold in August = 25
(b)
Total number of foolscaps sold in November as compared to October
= 100% - 10%
= 90%
100% → 40
1% → 40 ÷ 100 = 0.4
90% → 90 x 0.4 = 36
Number of foolscaps sold in November = 36
Answer(s): 25; (b) 36
