Mr Luis sold some kiwis, mangosteens and chikoos. The ratio of the number of kiwis sold to the total number of fruits sold was 3 : 10. The ratio of the number of mangosteens sold to the number of chikoos sold was 1 : 13. He sold 70 more chikoos than kiwis. Find the total number of fruits that he sold.

13 u |
20 u |
The total number of mangosteens and chikoos is repeated. Make the total number of mangosteens and chikoos the same. LCM of 7 and 14 is 14.
Number of more chikoos than kiwis
= 13 u - 6 u
= 7 u
7 u = 70
1 u = 70 ÷ 7 = 10
Total number of fruits that Mr Luis sold
= 20 u
= 20 x 10
= 200
Answer(s): 200
