Question

If the cost of a book worth ₹50 is increased by ₹25, then the percentage increase in its price is _____ .

• A. $25\%$
• B. $20\%$
• C. $50\%$
• D. $10\%$

Answer 1

The correct option is C

$50\%$

Original cost of the book = ₹50
Amount by which cost of the book is increased = ₹25
i.e., the amount of change = ₹25
$Percentageincrease=\frac{Amountofchange}{Originalcost}\times 100=\frac{25}{50}\times 100=50\%$
