Mr Ken sold some pears, starfruits and chikoos. The ratio of the number of pears sold to the total number of fruits sold was 2 : 7. The ratio of the number of starfruits sold to the number of chikoos sold was 1 : 14. He sold 72 more chikoos than pears. Find the total number of fruits that he sold.

The total number of starfruits and chikoos is repeated. Make the total number of starfruits and chikoos the same. LCM of 5 and 15 is 15.
Number of more chikoos than pears
= 14 u - 6 u
= 8 u
8 u = 72
1 u = 72 ÷ 8 = 9
Total number of fruits that Mr Ken sold
= 21 u
= 21 x 9
= 189
Answer(s): 189
