SOLUTION

We need to find the value which is $$x$$% more than $$y$$.

Thus, we need to find the value of $$y$$+$$\frac{x}{100}$$ * $$y$$.

Statement-1: “$$x$$% of $$y$$ is $$9$$”.

• $$\frac{x}{100}$$ * $$y$$=$$9$$……………………(1)

Since we don’t know the value of $$x$$ and $$y$$, statement 1 alone is not sufficient to answer the question.

Statement-2: “$$y$$% more than $$x$$ is $$24$$”.

• $$x$$+ $$\frac{y}{100}$$*$$x$$=$$24$$…………………….(2)

Since we don’t know the value of $$x$$ and $$y$$, statement 2 alone is not sufficient to answer the question.

Combining both the statements:

• $$x$$+ $$\frac{x*y}{100}$$ = $$24$$

• $$x+9=24$$

• $$x=15$$
Putting the value of $$x$$ in equation $$1$$

• $$\frac{x*y}{100}$$=$$9$$

• $$15$$*$$\frac{y}{100}$$=$$9$$

• $$y=60$$

We now have the value of $$x$$ and $$y$$ both. Hence, we can find the asked value.

Statement (1) and (2) together are sufficient.
