Mr Nick sold some kiwis, mangoes and starfruits. The ratio of the number of kiwis sold to the total number of fruits sold was 3 : 8. The ratio of the number of mangoes sold to the number of starfruits sold was 1 : 9. He sold 18 more starfruits than kiwis. Find the total number of fruits that he sold.

The total number of mangoes and starfruits is repeated. Make the total number of mangoes and starfruits the same. LCM of 5 and 10 is 10.
Number of more starfruits than kiwis
= 9 u - 6 u
= 3 u
3 u = 18
1 u = 18 ÷ 3 = 6
Total number of fruits that Mr Nick sold
= 16 u
= 16 x 6
= 96
Answer(s): 96
