Question

( frac{5 x-3}{x}+frac{5 y-3}{y}+frac{5 z-3}{3}=0 )
( Rightarrow 5-frac{3}{x}+5-frac{3}{y}+5-frac{3}{8}=0 )
( =15=3left(frac{1}{x}+frac{1}{y}+frac{1}{3}right) )
( Rightarrow frac{1}{x}+frac{1}{y}+frac{1}{3}=5 )

# 5x-3 "x (A) 5 (C) 15 5y-3 y 52-3 z + = 0, value of -+-+- is: 1 1 1 uvalue os xyz" (B) 10 (D) 3
