Question

Two-fifth of one-third of three-seventh of a number is 32. Then what is 30% of the number?

• A. 9.6
• B. 96
• C. 168
• D. 224

Answer 1

The correct option is C 168

Let the number be=x
Then, $x\times \frac{2}{5}\times \frac{1}{3}\times \frac{3}{7}=32$
$\Rightarrow x=32\times \frac{7}{3}\times 3\times \frac{5}{2}=560$
$\Rightarrow 30\%$ of $x=\frac{30}{100}\times 560=168$
