Mr Jeremy sold some mangosteens, pomegranates and pears. The ratio of the number of mangosteens sold to the total number of fruits sold was 2 : 5. The ratio of the number of pomegranates sold to the number of pears sold was 2 : 13. He sold 9 more pears than mangosteens. Find the total number of fruits that he sold.

The total number of pomegranates and pears is repeated. Make the total number of pomegranates and pears the same. LCM of 3 and 15 is 15.
Number of more pears than mangosteens
= 13 u - 10 u
= 3 u
3 u = 9
1 u = 9 ÷ 3 = 3
Total number of fruits that Mr Jeremy sold
= 25 u
= 25 x 3
= 75
Answer(s): 75
