Question

the price of a pencil has increased from 75 paise to 1 rupee. by how much percent has the price of pencil increased?​

Answer 1

Answer:

Original price = 75 p = Rs 0.75 ( 100 p = 1 rupee)

New price = Rs 1

------------------------------------------------------------------------

Increase in price = Rs 1 - 0.75

= Rs 0.25

------------------------------------------------------------------------

Percentage increase =

$\frac{increase}{original \: price} \times 100$

$\frac{0.25}{0.75} \times 100$

$\frac{1}{3} \times 100$

$33.3\%$

------------------------------------------------------------------------

Therefore, Percentage increase = 33.33%
