Question

If one-third of a number is $10$ more than one-fourth of the same number, what is $60$% of that number?

• A. $144$
• B. $24$
• C. $18$
• D. $72$

Answer 1

Answer: (D)

$72$

Let the number be $x$.
According to the question,
$\because \frac{x}{3}-\frac{x}{4}=10\Rightarrow \frac{x}{12}=10$
$\therefore x=10\times 12=120$
Hence, $60$% of the number $=\frac{60}{100}\times 120=72$.
