Risa had some kiwis and lemons in 2 crates. In Crate X, the number of kiwis to the number of lemons was in the ratio of 4 : 9. In Crate Y, there were four times as many kiwis as lemons. After Risa transferred ²₃ of the lemons from Crate X to Crate Y, the number of fruits left in Crate X was 133 and the ratio of the number of kiwis to the number of lemons in Crate B became 5 : 6. How many fruits were in Crate Y in the end?

	Crate X		Crate Y
	Kiwis	Lemons	Kiwis	Lemons
Before	4 u	9 u	4x5 =  20 p	1x5 = 5 p
Change		- 6 u		+ 6 u (+ 19 p)
After	4 u	3 u	5x4 = 20 p	6x4 = 24 p

Number of lemons that Risa transferred from Crate X to Crate Y
= ²₃ x 9 u
= 6 u

Total number of fruits in Crate X in the end
= 4 u + 3 u
= 7 u

7 u = 133
1 u = 133 ÷ 7 = 19

The number of kiwis in Crate Y is the unchanged quantity.
LCM of 4 and 5 is 20.

Number of lemons that Risa transferred from Crate X to Crate Y
= 6 u
= 6 x 19
= 114

Increase in the number of lemons that due to the transfer from Crate X to Crate Y
= 24 p - 5 p
= 19 p

19 p = 6 u 
19 p = 114

1 p = 114 ÷ 19 = 6

Number of fruits in Crate Y in the end
= 20 p + 24 p
= 44 p
= 44 x 6
= 264

Answer(s): 264
