A Correct answer
Explanation

Let us assume that the price was Rs. X/kg. The price got a hike @ 25% as 125X/100. Now, the person was able to purchase 400/X, but due to the hike it would be 400 * 100/125X. As per the equation, 400/X - 400 * 100/125x = 20, i.e. X = 4 So, the increased price is 4 * 125/100 = 5 Rs/kg Option 1 is correct.
