While calculating the weight of a group of men, the weight of 63 kg of...
To solve this problem, let's assume the number of men in the group is 'n'.
Let the original total weight of the group be 'W'.
Let the original average weight of the group be 'A'.
Given that the weight of one member was mistakenly written as 83 kg instead of 63 kg, we can calculate the difference in weight as follows:
Difference in weight = (83 kg - 63 kg) = 20 kg
Since the average weight increased by half kg, the new average weight of the group is 'A + 0.5'.
Let's calculate the new total weight of the group using the new average weight:
New total weight = (A + 0.5) * n
We can also calculate the new total weight by considering the difference in weight:
New total weight = W + 20 kg
Since both expressions represent the new total weight of the group, we can equate them:
W + 20 kg = (A + 0.5) * n
Now, let's substitute the value of 'W' from the equation for the original average weight:
A * n = (A + 0.5) * n - 20 kg
Simplifying the equation, we get:
A * n = A * n + 0.5 * n - 20 kg
0.5 * n = 20 kg
n = 40
Therefore, the number of men in the group is 40.

n = 40
Therefore, the number of men in the group is 40.
