Mr Ken sold some mangoes, kiwis and lemons. 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 lemons sold was 5 : 23. He sold 33 more lemons than mangoes. Find the total number of fruits that he sold.

The total number of kiwis and lemons is repeated. Make the total number of kiwis and lemons the same. LCM of 7 and 28 is 28.
Number of more lemons than mangoes
= 23 u - 12 u
= 11 u
11 u = 33
1 u = 33 ÷ 11 = 3
Total number of fruits that Mr Ken sold
= 40 u
= 40 x 3
= 120
Answer(s): 120
