The price of petrol was $₹65$. The price was first increased by $4\%$ and then reduced by $5\%$. What is the price of petrol now?

Answer 1

Finding the new price of petrol:

The price of petrol was $₹65$.

The price of petrol was increased by $4\%$.

Increase in price $=4\%\times 65=\frac{4}{100}\times 65=₹2.60$

New price of petrol $=\mathrm{Old}\mathrm{price}+\mathrm{Increas}e\mathrm{in}\mathrm{price}=65+2.60=₹67.60$

So, the price of petrol was $₹67.60$

Now, The price of petrol was reduced by $5\%$.

Decrease in price $=5\%\times 67.60=\frac{5}{100}\times 67.60=₹3.38$

Final price of petrol $=\mathrm{Increased}\mathrm{price}-\mathrm{Decrease}\mathrm{in}\mathrm{price}=67.60-3.38=₹64.22$

Hence, the price of petrol now is $₹64.22$
