The total number of passion fruits and starfruits is repeated. Make the total number of passion fruits and starfruits the same. LCM of 5 and 15 is 15.
Number of more starfruits than oranges
= 13 u - 6 u
= 7 u
7 u = 56
1 u = 56 ÷ 7 = 8
Total number of fruits that Mr Tim sold
= 21 u
= 21 x 8
= 168
Answer(s): 168
