MCQ
Mark $(\checkmark)$ tick against the correct answer in the following:
$\bigg\{6^{-1}+\Big(\frac{3}{2}\Big)^{-1}\bigg\}=?$
$\bigg\{6^{-1}+\Big(\frac{3}{2}\Big)^{-1}\bigg\}=?$
- A$\frac{2}{3}$
- B$\frac{5}{6}$
- ✓$\frac{6}{5}$
- DNone of these.
$\bigg\{6^{-1}+\Big(\frac{3}{2}\Big)^{-1}\bigg\}=\bigg[\Big(\frac{1}{6}\Big)+\Big(\frac{2}{3}\Big)\bigg]^{-1}$
$=\Big(\frac{1+4}{6}\Big)^{-1}=\Big(\frac{5}{6}\Big)^{-1}$
$=\frac{6}{5}$
