Mr Zane sold some persimmons, apples and oranges. The ratio of the number of persimmons sold to the total number of fruits sold was 2 : 9. The ratio of the number of apples sold to the number of oranges sold was 5 : 9. He sold 45 more oranges than persimmons. Find the total number of fruits that he sold.

The total number of apples and oranges is repeated. Make the total number of apples and oranges the same. LCM of 7 and 14 is 14.
Number of more oranges than persimmons
= 9 u - 4 u
= 5 u
5 u = 45
1 u = 45 ÷ 5 = 9
Total number of fruits that Mr Zane sold
= 18 u
= 18 x 9
= 162
Answer(s): 162
