Indian Economy - Understanding the basics of Indian economic system

When the price of rice decrease by 10%, a girl could buy 1 kg more for Rs. 270. Then, the original price of the rice per kg is

Rs. 30

Rs. 36

Rs. 42

Rs. 50

From the given data,

When the price of rice is decreased by 10%, the value of Rs. 270 would become

270 x 100/90 = 300

Now, the value 270 becomes 300

And given, the girl could buy 1 kg extra for that value

Change in value = 300 - 270 = Rs. 30

Therefore, 1 kg extra rice she can get for Rs. 30

= The original price of rice = Rs. 30/kg.

As she gets only 9 kgs for Rs. 270 before 10% discount,

now after discount she gets 10 kgs instead of 9 kgs for Rs. 270.

Hence, option 1 is the correct answer.
