PSLE Look at the graph and answer the following questions.
- How many post-it pads did the shop sell in March?
- The number of post-it pads sold in May was an 80% increase from the number sold in April. How many post-it pads were sold in May?
(a)
Number of post-it pads sold in March = 20
(b)
Total number of post-it pads sold in May as compared to April
= 100% + 80%
= 180%
100% → 45
1% → 45 ÷ 100 = 0.45
180% → 180 x 0.45 = 81
Number of post-it pads sold in May = 81
Answer(s): (a) 20; (b) 81
