Mr Harry sold some oranges, mangoes and apples. The ratio of the number of oranges sold to the total number of fruits sold was 2 : 7. The ratio of the number of mangoes sold to the number of apples sold was 1 : 9. He sold 30 more apples than oranges. Find the total number of fruits that he sold.

The total number of mangoes and apples is repeated. Make the total number of mangoes and apples the same. LCM of 5 and 10 is 10.
Number of more apples than oranges
= 9 u - 4 u
= 5 u
5 u = 30
1 u = 30 ÷ 5 = 6
Total number of fruits that Mr Harry sold
= 14 u
= 14 x 6
= 84
Answer(s): 84
