    Two numbers are respectively 20% and 40% more than a third number. What per cent is the first number of the second?

    A) \[85\frac{5}{7}\]%       

    B) \[75\frac{1}{7}\]%

    C) 85%                            

    D) \[85\frac{1}{7}\]%

    Correct Answer: A

    Solution :

    Let the third number \[=x\] Then, first number \[=120%\text{ of}\,x\]             \[=\frac{120x}{100}=\frac{6x}{5}\] and the second number \[=140%\text{ of}\,x\]             \[=\frac{140\times x}{100}=\frac{7x}{5}\] Required percentage \[=\frac{\frac{6x}{5}}{\frac{7x}{5}}\times 100%=\frac{600}{7}%=85\frac{5}{7}%\]
