The number of starfruits in the end is repeated. Make the number of starfruits in the end the same. LCM of 1 and 5 is 5.
Total number of oranges and starfruits at first
= 4 u - 39 + 20 u
= 24 u - 39
24 u - 39 = 201
24 u = 201 + 39
24 u = 240
1 u = 240 ÷ 24 = 10
Number of more starfruits than oranges at first
= 20 u - (4 u - 39)
= 20 u - 4 u + 39
= 16 u + 39
= 16 x 10 + 39
= 160 + 39
= 199
Answer(s): 199
