Julian, Albert and Clifford collected beads in the ratio of 7 : 4 : 10. After Clifford gave ⁷₁₀ to Julian and Albert, Clifford had 470 less beads than Julian. The number of beads that Albert had increased by 40%. How many beads did Julian and Clifford have in the end?

	Julian	Albert	Clifford
Before	7 u	4 u	10 u
Change	+ 5.4 u	+ 1.6 u	- 7 u
After	12.4 u	5.6 u	3 u

Number of beads that Clifford gave to Julian and Albert
= ⁷₁₀ x 10 u
= 7 u

Number of beads that Albert received from Clifford
= ⁴⁰₁₀₀ x 4 u
= 1.6 u

Number of beads that Julian received from Clifford
= 7 u - 1.6 u
= 5.4 u

Number of less beads that Clifford had less than Julian
= 12.4 u - 3 u 
= 9.4 u

9.4 u = 470

1 u = 470 ÷ 9.4 = 50

Number of beads that Julian and Clifford had
= 12.4 u + 3 u
= 15.4 u
= 15.4 x 50
= 770

Answer(s): 770
