The number of gold sweets is repeated. Make the number of gold sweets the same.
4 x 3 = 12%
Total number of yellow sweets and black sweets in percent
= 100% - 12%
= 88%
Number of black sweets in percent
= 88% - 9%
= 79%
Number of more black sweets than gold sweets in percent
= 79% - 9%
= 67%
67% = 201
1% = 201 ÷ 67 = 3
Number of more black sweets than yellow sweets
= 79% - 9%
= 70%
= 70 x 3
= 210
Answer(s): 210
