Mr Lee sold some starfruits, mangoes and pomegranates. The ratio of the number of starfruits sold to the total number of fruits sold was 3 : 8. The ratio of the number of mangoes sold to the number of pomegranates sold was 4 : 21. He sold 24 more pomegranates than starfruits. Find the total number of fruits that he sold.

The total number of mangoes and pomegranates is repeated. Make the total number of mangoes and pomegranates the same. LCM of 5 and 25 is 25.
Number of more pomegranates than starfruits
= 21 u - 15 u
= 6 u
6 u = 24
1 u = 24 ÷ 6 = 4
Total number of fruits that Mr Lee sold
= 40 u
= 40 x 4
= 160
Answer(s): 160
