The sum of the three numbers is 546.The first number is 126, the second is 30% more than the first. find the third number.

From the condition of the task it follows that: a + b + c = 546, where

1. The first number a = 126

2. Let’s define the second number:

b = a + (a * 30%)

h = 126 + (126 * 30%) = 163.80

3. Determine the third number by substituting the known data into the equation:

126 + 163.8 + c = 546

289.8 + c = 546

s = 546 – 289.8

s = 256.2

Answer: the third number is 256.20.
