Question

the gemetrical mean of three numbers was computed as 6. It was subsequently found that ,in this computation , a no. 8 was wrongly read as 12.what is the correct geometric mean???

Answer 1

here sum => number * mean =>3*6=18
8 was wrongly read as 12 => 18-12+8
=>6+8=14
therefore the correct mean=14/3=>4.666

Answer 2

here sum =number *=3*6=18
8 was wrongly read as 12 = 18-12+8=6+8=14
therefore the correct answer was= 14/3= 4.666
