Warren, Asher and Charlie collected pens in the ratio of 9 : 4 : 6. After Charlie gave ⁴₅ to Warren and Asher, Charlie had 114 less pens than Warren. The number of pens that Asher had increased by 30%. How many pens did Warren and Charlie have in the end?

	Warren	Asher	Charlie
Before	9 u	4 u	6 u
Change	+ 3.6 u	+ 1.2 u	- 4.8 u
After	12.6 u	5.2 u	1.2 u

Number of pens that Charlie gave to Warren and Asher
= ⁴₅ x 6 u
= 4.8 u

Number of pens that Asher received from Charlie
= ³⁰₁₀₀ x 4 u
= 1.2 u

Number of pens that Warren received from Charlie
= 4.8 u - 1.2 u
= 3.6 u

Number of less pens that Charlie had less than Warren
= 12.6 u - 1.2 u 
= 11.4 u

11.4 u = 114

1 u = 114 ÷ 11.4 = 10

Number of pens that Warren and Charlie had
= 12.6 u + 1.2 u
= 13.8 u
= 13.8 x 10
= 138

Answer(s): 138
