Question

Find the the least integer value for which $40$% of that integer is greater than $9.6$.

• A. $4$
• B. $12$
• C. $20$
• D. $25$

Answer 1

The correct option is D $25$

$40\%$ of that integer is greater than $9.6$

$\Rightarrow 40\%$ of $x>9.6$

$\Rightarrow 0.40x>9.6$

$x>24$

Now solve by dividing both sides by $0.40$, we get

$x>24$

Notice that $x>24$.

That means that the smallest integer is $25$.

It cannot be $24$ because $x$ is greater than $24$.

The smallest integer bigger than $24$ is $25$ .
