Question

My mother says, in her childhood petrol was Rs. 10 a
litre. It is Rs.80 per litre today. By what percentage has
the price gone up​

Answer 1

Step-by-step explanation:

% increase =( current price - old price)/ old price ×(100)

= ((80-10 )/10 )×100 = 700%

Answer 2

Difference is 80-10=70rs

70/10 x 100 = 700%
