Question

Three-fifth of two-third of three-seventh of a number is $150$. What is $60$% of that number?

• A. $52.5$
• B. $875$
• C. $750$
• D. $525$

Answer 1

The correct option is D $525$

Let the number be x.
According to the question,
$\frac{3}{5}\times \frac{2}{3}\times \frac{3}{7}\times x=150$
$\Rightarrow x=\frac{150\times 7\times 5}{3\times 2}$ = $875$.
$\therefore$ $60$% of $875$ = $\frac{875\times 60}{100}$ = $525$
