Answer 1

Answer:

43.33%

Step-by-step explanation:

1 Dozen pencil = $15

20 Dozen pencil = 15 × 20

240 pencil = $300

CP : 240 pencil = $ 300

SP1 : for 100 pencil,

4 pencil = $6

1 pencil = (6÷4)

100 pencil = 100 × (6÷4) = $150

SP2 : remaining pencil = 140

1 pencil = $2

140 pencil = $280

Total SP = 150+280=430

profit% = ((430-300)÷300)×100 = 43.33%
