In a shop that sells sweaters, 96 yellow sweaters were sold and 10% of the remaining sweaters that were sold were white. Of the leftover, 50% of the sweaters sold were gold sweaters and the rest were silver sweaters. Given that the number of silver sweaters sold was 25% of the total number of sweaters sold, how many white and silver sweaters were sold altogether?

The total number of gold and silver shirts is the combined repeated identity. Make the total number of gold and silver shirts the same. LCM of 9 and 2 is 18.
The number of silver shirts is repeated. Make the number of silver shirts the same. LCM of 9 and 1 is 9.
Number of yellow sweaters
= 27 u - 2 u - 9 u
= 16 u
16 u = 96
1 u = 96 ÷ 16 = 6
Number of white and silver sweaters
= 2 u + 9 u
= 11 u
= 11 x 6
= 66
Answer(s): 66
