Mr Cole sold some mangoes, starfruits and apples. The ratio of the number of mangoes sold to the total number of fruits sold was 2 : 5. The ratio of the number of starfruits sold to the number of apples sold was 1 : 11. He sold 18 more apples than mangoes. Find the total number of fruits that he sold.

The total number of starfruits and apples is repeated. Make the total number of starfruits and apples the same. LCM of 3 and 12 is 12.
Number of more apples than mangoes
= 11 u - 8 u
= 3 u
3 u = 18
1 u = 18 ÷ 3 = 6
Total number of fruits that Mr Cole sold
= 20 u
= 20 x 6
= 120
Answer(s): 120
