A) 51 :52
B) 52 : 53
C) 51: 53
D) 52 : 55
Correct Answer: B
Solution :
Let selling price of an article is x and x + 3 Then cost price of article at a profit of 4% \[=\frac{x\times 100}{104}\] Cost price of article at a profit of 6% \[=\frac{(x+3)\times 100}{106}\] Now, \[\frac{x\times 100}{104}=\frac{(x+3)\times 100}{106}\] \[\Rightarrow \] \[\frac{x}{52}=\frac{x+3}{53}\] \[\Rightarrow \] \[53x=52x+156\] \[x=156\] Hence, Required ratio \[=\frac{156}{156+3}\] \[=\frac{156}{159}=\frac{52}{53}\]
