Last year the price per share of Stock X increased by k percent and the earnings per share of Stock X increased by m percent, where k is greater than m. By what percent did the ratio of price per share to earnings per share increase, in terms of k and m?
Choose the correct choice from the following choices: A) k/m % B) (k-m) % C) [100(k-m)]/(100+k) % D) [100(k-m)]/(100+m) % E) [100(k-m)]/(100+k+m) %
If old price per share = X, old Earnings per share = Y   =&gt; Old ratio = X/Y   New price per share = X(100+k)/100, new Earnings per share = Y(100+m)/100   =&gt;New ratio = X(100+K)/[(100+m)(Y)]   Increase in the ratios after simplifying comes to [100(k-m)]/(100+m) %   ANSWER:[100(k-m)]/(100+m) %
