Answer 2

Answer:

It is given that Mean of 31 results = 60 So the total sum = 31 (60) = 1860 We know that Mean of first 16 results = 58 So the total sum = 16 (58) = 928 Mean of last 16 results = 62 So the total sum = 16 (62) = 992 We get the 16th result = total sum of first 16 results + total sum of last 16 results – total sum of 31 results By substituting the values 16th result = 928 + 992 – 1860 On further calculation 16th result = 1920 – 1860 = 60 Therefore, the 16th result of 60.
