Mr Ivan sold some starfruits, mangosteens and lemons. The ratio of the number of starfruits sold to the total number of fruits sold was 3 : 8. The ratio of the number of mangosteens sold to the number of lemons sold was 3 : 17. He sold 30 more lemons than starfruits. Find the total number of fruits that he sold.

The total number of mangosteens and lemons is repeated. Make the total number of mangosteens and lemons the same. LCM of 5 and 20 is 20.
Number of more lemons than starfruits
= 17 u - 12 u
= 5 u
5 u = 30
1 u = 30 ÷ 5 = 6
Total number of fruits that Mr Ivan sold
= 32 u
= 32 x 6
= 192
Answer(s): 192
