A) 7%
B) 8%
C) 10%
D) 12.5%
Correct Answer: C
Solution :
Let C"s income \[=Rs.\,x\] \[\therefore \] B?s income \[=\frac{x\times 75}{100}=Rs.\frac{3x}{4}\] and A?s income \[=\frac{3x}{4}\times \frac{120}{100}=Rs.\frac{9x}{10}\] \[\therefore \] Required percentage \[=\frac{x-\frac{9x}{10}}{x}\times 100=10%\] Hence, A's income is 10% less than Cs income.You need to login to perform this action.
