The number of blue chocolate bars is repeated. Make the number of blue chocolate bars the same.
5 x 7 = 35%
Total number of yellow chocolate bars and pink chocolate bars in percent
= 100% - 35%
= 65%
Number of pink chocolate bars in percent
= 65% - 28%
= 37%
Number of more pink chocolate bars than blue chocolate bars in percent
= 37% - 28%
= 2%
2% = 20
1% = 20 ÷ 2 = 10
Number of less yellow chocolate bars than pink chocolate bars
= 37% - 28%
= 9%
= 9 x 10
= 90
Answer(s): 90
