Three numbers when added together equal 999. If the second number is twice the first number, and the third number is half the first number, what is the value of the first number?

Answer 1

S=2F, T=F/2

F+S + T = 999

F+2F + F/2 = 999

7F/2 = 999

F = (2/7)999 = 285.43

S=570.86

T = 142.71

285.43+570.86+142.71= 999.00
