Mr Simon sold some apples, chikoos and oranges. The ratio of the number of apples sold to the total number of fruits sold was 3 : 7. The ratio of the number of chikoos sold to the number of oranges sold was 1 : 15. He sold 15 more oranges than apples. Find the total number of fruits that he sold.

The total number of chikoos and oranges is repeated. Make the total number of chikoos and oranges the same. LCM of 4 and 16 is 16.
Number of more oranges than apples
= 15 u - 12 u
= 3 u
3 u = 15
1 u = 15 ÷ 3 = 5
Total number of fruits that Mr Simon sold
= 28 u
= 28 x 5
= 140
Answer(s): 140
