Here is complete explanation of The average age of 11 players of a cricket team is….

Solution(By ExamCraze 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,
$$eqalign{ & Rightarrow 11x + y - 18 - 20 = 11left( {x + frac{1}{6}} right) cr & Rightarrow 11x + y - 38 = 11x + frac{{11}}{6} cr & Rightarrow y = frac{{11}}{6} + 38 cr & Rightarrow y = frac{{239}}{6} cr} $$
∴ Average
$$eqalign{ & = frac{{239}}{{2 times 6}} cr & = frac{{239}}{{12}} cr} $$
= 19 years 11 months
