Mr Riordan sold some kiwis, oranges and mangoes. The ratio of the number of kiwis sold to the total number of fruits sold was 3 : 8. The ratio of the number of oranges sold to the number of mangoes sold was 6 : 19. He sold 36 more mangoes than kiwis. Find the total number of fruits that he sold.

The total number of oranges and mangoes is repeated. Make the total number of oranges and mangoes the same. LCM of 5 and 25 is 25.
Number of more mangoes than kiwis
= 19 u - 15 u
= 4 u
4 u = 36
1 u = 36 ÷ 4 = 9
Total number of fruits that Mr Riordan sold
= 40 u
= 40 x 9
= 360
Answer(s): 360
