If $f(x)=[8 x]-3$, where $[x]$ is greatest integer function of $x$, then $\mathrm{f}(\pi)=$

If $f(x)=[8 x]-3$, where $[x]$ is greatest integer function of $x$, then $\mathrm{f}(\pi)=$
  1. 21
  2. 25
  3. 23
  4. 22

Solution

$f(x)=[8 x]-3$ $\therefore \mathrm{f}(\pi)=[8(3.14)]-3=[25.12]-3=25-3=22$
