Mr Jenson sold some apples, starfruits and mangoes. The ratio of the number of apples sold to the total number of fruits sold was 3 : 8. The ratio of the number of starfruits sold to the number of mangoes sold was 1 : 9. He sold 21 more mangoes than apples. Find the total number of fruits that he sold.

The total number of starfruits and mangoes is repeated. Make the total number of starfruits and mangoes the same. LCM of 5 and 10 is 10.
Number of more mangoes than apples
= 9 u - 6 u
= 3 u
3 u = 21
1 u = 21 ÷ 3 = 7
Total number of fruits that Mr Jenson sold
= 16 u
= 16 x 7
= 112
Answer(s): 112
