15

I hope you know that if some number $a$ $a$ is some $c %$ $c%$ of a number $b$ $b$ then $\frac{a}{b} \cdot 100 = c$ $color(red)(a/b*100 = c)$

Let $51$ $51$ be $340 %$ $340%$ of some number say $x$ $color(red)(x)$ .

Then,

$\frac{51}{x} \cdot 100 = 340$ $51/x*100 = 340$

$\Rightarrow \frac{51}{340} \cdot 100 = x$ $=> 51/340*100 = x$

$\Rightarrow x = 15$ $=> x = 15$

Hence $51$ $51$ is $340 %$ $340%$ of $15$ $15$ .
