Answer 1

Question:

The price of petrol is increased from rs.75 per litre to rs.82.50. By how many percent is the price increased?

Answer:

The cost of the petrol is increased by 10%.

Given:

The price of petrol is increased from rs.75 per litre to rs.82.50.

To find:

The increased rate of the cost of the petrol.

Explanation:

The price of petrol is increased from rs.75 per litre to rs.82.50.

∴ Increased amount = rs. (82.50 - 75.00)

                                  = rs. 7.50

∴ Increased rate = $(\frac{7.50}{75}$ × $100)$

                            = $(\frac{750}{75})$

                            = 10% [∵ Dividing 750 and 75 by 75.]

∴ The price of the petrol is increased by 10%.

Answer 2

Answer:

Price is increased by 10%.

Step-by-step explanation:

We are given that the price of petrol is increased from Rs. 75 per litre to Rs. 82.50 per litre .

Increase in Price = Rs (82.50 - 75) = Rs 7.5

Percentage Increase = (Increase in price ÷ Original price) * 100

                                   = $\frac{7.5}{75} *100$ = 10%

Therefore,  price is increased by 10%.
