The weight of a body as calculated by the average of 7 different experiments is 53.735 g. The average of the first three experiments is 54.005 g, of the fourth is 0.004 g greater than the fifth, while the average of the sixth and seventh experiment was 0.010 g less than the average of the first three. Find the weight of the body obtained by the fourth experiment.

- total sum of 7 experiments weights=7*53.735
total sum of First 3 experiments weights=3*54.005
Weight of 5th Experiment = Xkg
Weight of 4th Experiment = X+0.004kg
total sum of 6th and 7th experiments weights=2*53.995
So the Solution For the Question Given Below ,
7*53.735=3*54.005+X+(X+0.004)+2*53.995,
So, 2X=106.676
X=53.338
So 4th Experiment Weight = X + 0.004=53.342
