The sum of three numbers is 1000. One of the numbers, Z, is 50% more than the sum of the other two numbers. What is the value of Z ?
Choice B is correct.
Let the three numbers be X, Y, Z.
According to the question Z = 1.5 (X + Y)
Also, X + Y + Z = 1000
Therefore, Z/1.5 + Z = 1000
Or 5Z/3 = 1000
Or Z = 600.
