Question

Due to a price hike of 20%, 4 kg less sugar are available for Rs. 120. What is the initial price per kg of sugar?

Answer 1

Answer:

5

Step-by-step explanation:

xy = 120

and

1.2x * (y-4) = 120

=> 1.2xy - 4.8x = 120

=> 1.2*120 - 4.8x = 120

=> 4.8x = 144 - 120

=> x = 24/4.8

=> x = 5
