Mrs Sofia baked 144 chicken floss buns, some yam buns and some custard buns. The ratio of the number of yam buns to the number of custard buns was 5:4. There were 24 more yam buns than custard buns. What percentage of the buns were chicken floss buns?

Answer 1

Let's denote the number of yam buns as 5x and the number of custard buns as 4x.

According to the question, 5x = 4x + 24
x = 24

Therefore, the number of yam buns is 5(24) = 120 and the number of custard buns is 4(24) = 96.

The total number of buns is 144, so the number of chicken floss buns is 144 - 120 - 96 = 24.

Therefore, the percentage of chicken floss buns is (24/144) x 100% = 16.67%.
