The sum of three numbers is 855. One of the numbers, x, is 50% more than the sum of the other two numbers. What is the value of x?

The value of x = 513

Step-by-step explanation:

Let x, y, and z be the three numbers

Given

Assuming x be the number which is 50% more than the sum of the other two numbers.

i.e.

(150)% of (y+z) = 1.5(y+z)

                y + z = x/1.5

As we know that

substituting y + z = x / 1.5 in the equation

Multiply both sides by 1.5

Divide both sides by 2.5

Therefore, the value of x = 513

3 is greater then both of those numbers
