The average weight of the first 11 persons out of 12 is 95 kg. The 12th person’s weight is 33 kg more than the average weight of all 12 persons. What is the weight of the 12th person?

Let the average weight of all 12 persons be $x$ kg.

Step 1: Total weight of first 11 persons

Average of first 11 = 95 kg
So, total weight = $11 \times 95 = 1045$ kg

Step 2: Weight of 12th person

Given: 12th person is 33 kg more than average of all 12

So,
12th weight = $x + 33$

Step 3: Total weight equation

Total of 12 persons:
$1045 + (x + 33) = 12x$

Step 4: Solve

$1078 + x = 12x$

$1078 = 11x$

$x = 98$

Step 5: 12th person weight

$x + 33 = 98 + 33 = 131$

Final Answer: 131 kg
