PSLE Look at the graph and answer the following questions.
- How many notebooks did the shop sell in February?
- The number of notebooks sold in May was an 10% decrease from the number sold in April. How many notebooks were sold in May?
(a)
Number of notebooks sold in February = 25
(b)

1% → 30 ÷ 100 = 0.3
90% → 90 x 0.3 = 27
Number of notebooks sold in May = 27
Answer(s): 25; (b) 27
