Solution(By Apex Team)

Total age of 2 players = 18 + 20 = 38 years Increased years = 2 × 11 = 22 months Age of new players = 38 years + 22 months = 39 years 10 months Average = 19 years 11 months
Alternate: Let the total age of 11 players = 11x Then the sum of age of new players = y years According to the question, $\begin{aligned}&\Rightarrow11x+y-18-20=11\left(x+\frac{1}{6}\right)\\ &\Rightarrow11x+y-38=11x+\frac{11}{6}\\ &\Rightarrow y=\frac{11}{6}+38\\ &\Rightarrow y=\frac{239}{6}\\ &\text{ Average }\\ &=\frac{239}{2\times6}\\ &=\frac{239}{12}\end{aligned}$ = 19 years 11 months
