Mr Jenson sold some oranges, apples and mangosteens. The ratio of the number of oranges sold to the total number of fruits sold was 3 : 10. The ratio of the number of apples sold to the number of mangosteens sold was 1 : 13. He sold 84 more mangosteens than oranges. Find the total number of fruits that he sold.

The total number of apples and mangosteens is repeated. Make the total number of apples and mangosteens the same. LCM of 7 and 14 is 14.
Number of more mangosteens than oranges
= 13 u - 6 u
= 7 u
7 u = 84
1 u = 84 ÷ 7 = 12
Total number of fruits that Mr Jenson sold
= 20 u
= 20 x 12
= 240
Answer(s): 240
