Mr Henry sold some mangoes, kiwis and persimmons. The ratio of the number of mangoes sold to the total number of fruits sold was 3 : 10. The ratio of the number of kiwis sold to the number of persimmons sold was 5 : 16. He sold 28 more persimmons than mangoes. Find the total number of fruits that he sold.

The total number of kiwis and persimmons is repeated. Make the total number of kiwis and persimmons the same. LCM of 7 and 21 is 21.
Number of more persimmons than mangoes
= 16 u - 9 u
= 7 u
7 u = 28
1 u = 28 ÷ 7 = 4
Total number of fruits that Mr Henry sold
= 30 u
= 30 x 4
= 120
Answer(s): 120
