The value of \(\frac{(0.42)^{2}+36(0.05)^{2}}{9(0.21)^{2}+(0.45)^{2}}\) is
\( \frac{2}{9} \)
\( \frac{5}{18} \)
\( \frac{2}{3} \)
\( \frac{4}{9} \)
Aditya can complete a piece of work alone in 8 days and Bhagawan can complete the same piece of work alone in 12 days. They started the work together, but Aditya had to leave 3 days before the completion of the work. In how many days will the work be complete?
6 \( \frac{3}{5} \) days
6 \( \frac{4}{5} \) days
6 \( \frac{1}{5} \) days
6 \( \frac{2}{5} \) days

If(\(\sqrt{2352}\) ÷ \(\sqrt{1200}\) ) ÷ \(\sqrt{0.04}\), then the value of \( \frac{x+1}{x-1} \) is :
\( \frac{3}{2} \)
\( \frac{4}{3} \)
\( \frac{2}{3} \)
\( \frac{3}{4} \)
