Question

The price of petrol increased from Rs 48 to rs 53.76.

Answer 1

Answer:

12%

Step-by-step explanation:

As per the provided information in the given question, we have :

• Original price of petrol = Rs. 48
• New price of petrol = Rs. 53.76

We are asked to calculate,

• Percentage increase

As we know that,

$\\ \longrightarrow \sf{\quad { \% \; increase =\Bigg ( \dfrac{Price \; increase}{Original \; price} \times 100 \Bigg ) \; \%}}$

→ Price increase = New price - Original price

→ Price increase = Rs. ( 53.76 - 48 )

→ Price increase = Rs. 5.76

Substituting values,

$\\ \longrightarrow \sf{\quad { \% \; increase =\Bigg ( \dfrac{5.76}{48} \times 100 \Bigg ) \; \%}}$

$\\ \longrightarrow \sf{\quad { \% \; increase =\Bigg ( \dfrac{576}{4800} \times 100 \Bigg ) \; \%}}$

$\\ \longrightarrow \sf{\quad { \% \; increase =\Bigg ( \dfrac{57600}{4800} \Bigg ) \; \%}}$

$\\ \longrightarrow \sf{\quad { \% \; increase =\Bigg ( \dfrac{576}{48} \Bigg ) \; \%}}$

$\\ \longrightarrow \bf{\quad\underline { \% \; increase = 12\; \%}}$

Therefore, percentage increase is 12 %.
