Correct answer: (E) None of the aboveउपर्युक्त में से कोई नहीं

Explanation

From 3 tan θ = 4, tan θ = 4/3. Dividing numerator and denominator by cos θ gives (3·4/3 + 2)/(3·4/3 − 2) = 6/2 = 3, which is not among the options.3 tan θ = 4 से tan θ = 4/3। अंश और हर में cos θ से भाग देने पर (3·4/3 + 2)/(3·4/3 − 2) = 6/2 = 3, जो विकल्पों में नहीं है।
