Starting from point P, Sheetal walks 50 m towards the west. She takes a right turn and walks 20 m. Then she takes a left turn and walks 47 m. She takes a left turn again and walks 75 m. Again, she takes a left turn and walks 47 m. She takes a left turn again and walks 20 m. Then she takes a right turn and walks 50 m. Finally, she takes a left turn and walks 10 m to reach point Q. How far and in which direction is point P from point Q? (All turns are 90° turns only.)
35 m due north
25 m due north
25 m due south
15 m due north
Find the value of \(\left(\frac{64}{25}\right)^{-\frac{3}{2}}\times\left(\frac{2}{5}\right)^4\div\sqrt[5]{(32)^{-3}}\) is:
\(\frac{8}{25}\)
\(\frac{1}{20}\)
\(\frac{1}{5}\)
\(\frac{1}{10}\)
