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

1% → 40 ÷ 100 = 0.4
75% → 75 x 0.4 = 30
Number of post-it pads sold in May = 30
Answer(s): 10; (b) 30
