Answer 2

Answer:

5100%

Step-by-step explanation:

My mother says in her childhood petrol was Rupees 1 hour later it is rupees 52.

Change in price = Current price of petrol - Price of petrol in childhood

= Rs. 52 - Rs. 1

= Rs. 51

We have to find the increase in percentage.

Increased percentage = (Change in price)/(Price of petrol in childhood) × 100

= 51/1 × 100

= 5100%

Hence, the percentage has price gone up by 5100%.
