Answer 3

Calculation of Sergey's Weight

To calculate Sergey's weight, we need to determine the average weight of boys of the same age and then use that information to find Sergey's weight.

Given that the average weight of boys of the same age as Sergey is 48 kg and Sergey's weight is 120% of the average weight, we can calculate Sergey's weight as follows:

Step 1: Calculate Sergey's weight as a percentage of the average weight: - Sergey's weight = 120% of the average weight

Step 2: Calculate Sergey's weight using the average weight: - Sergey's weight = (120/100) * average weight

Now, let's substitute the given average weight of boys (48 kg) into the formula to find Sergey's weight:

Sergey's weight = (120/100) * 48 kg

Simplifying the equation:

Sergey's weight = 1.2 * 48 kg

Calculating the result:

Sergey's weight = 57.6 kg

Therefore, Sergey weighs 57.6 kg.
