​

Answer 1

Answer:

Initial price of rice was Rs.100 per kg

Step-by-step explanation:

After a 20% increase a person can have 5 kg of rice for Rs.600

=> New price of rice in Rs per kg = 600 / 5 = 120

There has been a 20% rise in price.

=> New Price = Old Price + 20% of Old Price

=> New Price = Old Price + 0.2*Old Price

=> New Price = 1.2*(Old Price)

New Price = 120

=> 120 = 1.2*(Old Price)

=> Old Price = 120/1.2 = 100

Initial price of rice was Rs.100 per kg
