Correct Answer: Option C

Explanation

3\(\frac{1}{2}\) - (2\(\frac{1}{3}\) x 1\(\frac{1}{4}\)) + \(\frac{3}{5}\))
= \(\frac{7}{2}\) - (\(\frac{7}{3}\) x \(\frac{5}{4}\)) + \(\frac{3}{5}\))
= \(\frac{7}{2}\) - \(\frac{35}{12}\) + \(\frac{3}{5}\)
= L.C.M = 60
= \(\frac{(210 - 175 + 36)}{60}\)
= \(\frac{71}{60}\)
= 1\(\frac{11}{60}\)
