In a kiosk, some rubik's cubes and flying saucers were on sale. ¹₄ of the items were rubik's cubes. ²₃ of the rubik's cubes and 208 flying saucers were sold. There were ¹₉ of the items left in the kiosk. How many rubik's cubes and flying saucers were there in the kiosk at first?

	Rubik's cubes	Flying saucers	Total
Comparing rubik's cubes  and flying saucers at first	1x9 = 9 u	3x9 = 27 u	4x9 = 36 u
Before	3x3 =  9 u		9x4 = 36 u
Change	- 2x3 = - 6 u	- 208	- 8x4 = - 32 u
After	1x3 = 3 u	1 u	1x4 = 4 u

 
The total number of toys at first is repeated.  Make the total number of toys at first the same. LCM of 4 and 9 is 36.

The number of rubik's cubes at first is repeated.  Make the number of rubik's cubes the same. LCM of 9 and 3 is 9. 

Number of flying saucers left
= 4 u - 3 u
= 1 u

Number of flying saucers sold
= 27 u - 1 u
= 26 u

26 u = 208

1 u = 208 ÷ 26 = 8

Number of rubik's cubes and flying saucers at first
= 36 u
= 36 x 8
= 288

Answer(s): 288
