Mr Zane sold some pears, mangosteens and persimmons. The ratio of the number of pears sold to the total number of fruits sold was 3 : 10. The ratio of the number of mangosteens sold to the number of persimmons sold was 3 : 25. He sold 26 more persimmons than pears. Find the total number of fruits that he sold.

The total number of mangosteens and persimmons is repeated. Make the total number of mangosteens and persimmons the same. LCM of 7 and 28 is 28.
Number of more persimmons than pears
= 25 u - 12 u
= 13 u
13 u = 26
1 u = 26 ÷ 13 = 2
Total number of fruits that Mr Zane sold
= 40 u
= 40 x 2
= 80
Answer(s): 80
