The number of kiwis in the end is repeated. Make the number of kiwis in the end the same. LCM of 3 and 5 is 15.
Total number of lemons and kiwis at first
= 12 u - 22 + 20 u
= 32 u - 22
32 u - 22 = 554
32 u = 554 + 22
32 u = 576
1 u = 576 ÷ 32 = 18
Number of more kiwis than lemons at first
= 20 u - (12 u - 22)
= 20 u - 12 u + 22
= 8 u + 22
= 8 x 18 + 22
= 144 + 22
= 166
Answer(s): 166
