PSLE Look at the graph and answer the following questions.
- How many staplers did the shop sell in March?
- The number of staplers sold in May was an 10% increase from the number sold in April. How many staplers were sold in May?
(a)
Number of staplers sold in March = 30
(b)
Total number of staplers sold in May as compared to April
= 100% + 10%
= 110%
100% → 20
1% → 20 ÷ 100 = 0.2
110% → 110 x 0.2 = 22
Number of staplers sold in May = 22
Answer(s): (a) 30; (b) 22
