(3) 6%

(4) 8%

(5) 12%

Solution :

Step 1 of 2 :

Write down the given time

The given time is 3 minutes 36 seconds

3 minutes 36 seconds

Hence the required percentage

$\displaystyle \sf{ = \frac{216}{3600} \times 100\% }$

$\displaystyle \sf{ = \frac{216}{36} \: \% }$

$\displaystyle \sf{ = 6 \: \% }$

Hence the correct option is (3) 6%
