PSLE Look at the graph and answer the following questions.
- How many pens did the shop sell in March?
- The number of pens sold in May was an 60% increase from the number sold in April. How many pens were sold in May?
(a)
Number of pens sold in March = 15
(b)
Total number of pens sold in May as compared to April

1% → 20 ÷ 100 = 0.2
160% → 160 x 0.2 = 32
Number of pens sold in May = 32
Answer(s): (a) 15; (b) 32
