Answer 1

Answer:40

Step-by-step explanation:

Suppose if he purchased x kgs for 1200₹

Now after hike he got 6 kgs less so the equation would be like

(x-6)kgs for 1500₹(25% increase of 1200₹)

Now we can observe that after due to hike there is a difference in ₹300 for 6kgs

So that means after hike one kg would be ₹50

For 125% it is ₹50/kg

For 100% it would (100*50)/125= ₹40

Therefore it is ₹40/kg before hike
