What is 10% of 20% of 30% ?
Correct Answer: Option B
Solution:
10% এর 20% এর 30% = \(\frac{{10}}{{100}} \times \frac{{20}}{{100}} \times \frac{{30}}{{100}} = \frac{6}{{1000}}\) = 0.006 = 0.6%
Shortcut: যেহেতু উত্তরে % আছে, তাই একটি % রেখে এভাবেও করতে পারেনঃ \(\frac{{10}}{{100}} \times \frac{{20}}{{100}} \times 30\% = \frac{{60}}{{10}}\% \) = 0.6%
