Question

A merchant changed his trade discount from $25$% to $15$%. This would increase selling price by

• A. $3\frac{1}{3}$%
• B. $6\frac{1}{6}$%
• C. $13\frac{1}{3}$%
• D. $6\frac{1}{3}$%

Answer 1

Answer: (C)

$13\frac{1}{3}$%

Let the $MP$ be $Rs.100$.
Initial $SP=0.75\times 100=75$
New, $SP=0.85\times 100=85$
Percentage change $=\frac{85-75}{75}\times 100=\frac{10}{75}=13\frac{1}{3}$%.
