Harry had 75% fewer mochi balls than Sam. After Sam gave 232 mochi balls to Harry, Harry had ³₄ as many mochi balls as Sam. How many mochi balls did each of them have in the end?

1. Sam
2. Harry

	Harry	Sam	Total
Before	1x7 = 7 u	4x7 = 28 u	5x7 = 35 u
Change	+ 232	- 232
After	3x5 = 15 u	4x5 =  20 u	7x5 = 35 u

Number of mochi balls that Harry had at first in percentage
= 100% - 75%
= 25%

25% = ²⁵₁₀₀ = ¹₄

The total number of mochi balls at first and in the end remains unchanged. Make the total number of mochi balls the same. LCM of 7 and 5 is 35.

Number of mochi balls that Sam gave to Harry
= 28 u - 20 u
= 8 u

8 u = 232

1 u = 232 ÷ 8 = 29

Number of mochi balls that Harry had in the end
= 15 u
= 15 x 29
= 435

Number of mochi balls that Sam had in the end
= 20 u
= 20 x 29
= 580

Answer(s): (a) 435; (b) 580
