Comparing between

5x1 =

The number of oranges in the end is repeated. Make the number of oranges in the end the same. LCM of 1 and 5 is 5.
Total number of kiwis and oranges at first
= 2 u - 37 + 10 u
= 12 u - 37
12 u - 37 = 227
12 u = 227 + 37
12 u = 264
1 u = 264 ÷ 12 = 22
Number of more oranges than kiwis at first
= 10 u - (2 u - 37)
= 10 u - 2 u + 37
= 8 u + 37
= 8 x 22 + 37
= 176 + 37
= 213
Answer(s): 213
