15% of 10% of 20% of 1000 is

• A. $1.50$
• B. $67$
• C. $150$
• D. $3$

Answer 1

The correct option is D $3$

$15\%$ of $10\%$ of $20\%$ of $1000$

$\Rightarrow 15\%$ of $10\%[\frac{20}{100}\times 1000]$

$\Rightarrow 15\%$ of $10\%$ of $200$

$\Rightarrow 15\%[\frac{10}{100}\times 200]$

$\Rightarrow 15\%$ of $20$

$\Rightarrow \frac{15}{100}\times 20$

$\Rightarrow 3$

$\therefore 15\%$ of $10\%$ of $20\%$ of $1000=3$
