  1. The average age of eleven players of a cricket team decreases by 2 months when two new players are included in the team replacing two players of age 17 years and 20 years. The average age of new player is
    1. 17 years 1 month
    2. 17 years 7 months
    3. 17 years 11 months
    4. 18 years 3 months
Correct Option: B

According to question ,

Average age of new players = (20 + 17) 11 × 2× 1

Average age of new players = 422 = 211⇒ 177
12 × 21212

∴ Average age of new players = 17 years 7 months
