আমাদের আছে,
\(\rm \frac{2a-5}{a}-\frac{4b-5}{b}+\frac{6c+5}{c}=0\)
⇒ 2 - \(\frac{5}{a}\) - 4 + \(\frac{5}{b}\) + 6 + \(\frac{5}{c}\) = 0
⇒ 8 - 4 = \(\frac{5}{a}\) - \(\frac{5}{b}\) - \(\frac{5}{c}\)
⇒ 4 = 5 [\(\frac{1}{a}\) - \(\frac{1}{b}\) - \(\frac{1}{c}\) ]
⇒ [\(\frac{1}{a}\) - \(\frac{1}{b}\) - \(\frac{1}{c}\) ] = 4/5
∴ সঠিক উত্তর হল বিকল্প (1)
