Answer 2

Given Information:

- Сумма трех чисел равна 546. - Первое число равно 126. - Второе число на 30% больше первого.

Solution:

Let's solve this problem step by step.

Step 1: Find the second number. We know that the second number is 30% larger than the first number. To find the second number, we can calculate 30% of the first number and add it to the first number.

First number = 126 30% of the first number = 30/100 * 126 = 37.8

Second number = First number + 30% of the first number Second number = 126 + 37.8 = 163.8

So, the second number is 163.8.

Step 2: Find the third number. We are given that the sum of the three numbers is 546. To find the third number, we can subtract the sum of the first two numbers from 546.

Sum of the first two numbers = First number + Second number Sum of the first two numbers = 126 + 163.8 = 289.8

Third number = Sum of the three numbers - Sum of the first two numbers Third number = 546 - 289.8 = 256.2

So, the third number is 256.2.

Answer:

The third number is 256.2.
