calculate the percentage increase.
with calculation and the answer should be 12%

Answer 1

12%

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 ( (Price \; increase)/(Original \; price) * 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 ( (5.76)/(48) * 100 \Bigg ) \; \%}} \\`

`\\ \longrightarrow \sf{\quad { \% \; increase =\Bigg ( (576)/(4800) * 100 \Bigg ) \; \%}} \\`

`\\ \longrightarrow \sf{\quad { \% \; increase =\Bigg ( (57600)/(4800) \Bigg ) \; \%}} \\`

`\\ \longrightarrow \sf{\quad { \% \; increase =\Bigg ( (576)/(48) \Bigg ) \; \%}} \\`

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

Therefore, percentage increase is 12 %.
