The numbers are respectively $$12\frac{1}{2}\% $$  and $$25\% $$ more than a third number. The as a percentage of the second number is : Correct Answer 90%

Let the third number be $$x$$
Then, first number :
= $$112\frac{1}{2}\% $$  of $$x$$
= $$\frac{9x}{8}$$
Second number :
= 125% of $$x$$
= $$\frac{5x}{4}$$
∴ Required percentage :
= $$\left( {\frac{{9x}}{8} \times \frac{{4}}{{5x}} \times 100} \right)$$   %
= 90%
