Given mean of the distribution is 50.
Class fi xi fi * xi
0 - 20 17 10 170
20 - 40 G 30 30G
40 - 60 32 50 1600
60 - 80 24 70 1680
80 - 100 19 90 1710
------- ---------
92 + G 5160 + 30G
Now,
50 = 5160 + 30G/92+G
50(92 + G) = 5160 + 30G
4600 + 50G = 5160 + 30G
50G - 30G = 560
20G = 560
G = 560/20
G = 28.
Therefore the value of G = 28.
Hope this helps!
