The number of purple chocolate bars is repeated. Make the number of purple chocolate bars the same.
5 x 5 = 25%
Total number of blue chocolate bars and brown chocolate bars in percent
= 100% - 25%
= 75%
Number of brown chocolate bars in percent
= 75% - 15%
= 60%
Number of more brown chocolate bars than purple chocolate bars in percent
= 60% - 15%
= 35%
35% = 175
1% = 175 ÷ 35 = 5
Number of less blue chocolate bars than brown chocolate bars
= 60% - 15%
= 45%
= 45 x 5
= 225
Answer(s): 225
