The average guessed by all 50 children = 627.

∴ The total guessed by all 50 children = 50 × 627 = 31,350


The average guessed by 47 children = 627 - 114 = 513

∴ The total guessed by 47 children = 47 × 513 = 24,111


31,350 - 24,111 = 7,239


So, the three outliers guessed a total of 7,239

⇒ Their mean guess was 7,239 ÷ 3 = 2,413
