Show Answer

Solution(By Apex Team)

Sum of age of two players = 17 + 20 = 37 years Decreasing age of players = 11 × 2 = 22 months Sum of age of two new players = 37 years – 22 months = 35 years 2 months Average = 17 years 7 months
Alternate : $\begin{array}{l}\large\frac{(17+20)-(\text{ Sum of two new players })}{11}\\ =\large\frac{2}{12}\\ =\large\frac{1}{6}\end{array}$ Sum of two new players $\large=\frac{211}{6}$ Average of two new players $\large=\frac{211}{12}$ = 17 years 7 months
