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 \[=\frac{\frac{6x}{5}}{\frac{7x}{5}}\times 100%=\frac{600}{7}%=85\frac{5}{7}%\]You need to login to perform this action.
