The price of an item is reduced by 20%. As a result, customers can get 2 kg more of it for Rs 360. Find the original price (in Rs) per kg of the item.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 45
Calculations:
We know that 20% = 1/5 in fraction
So let the price be 5x
After reduction it will be 4x
As a result, customers can get 2 kg more of it for Rs 360
⇒ (360/4x) - (360/5x) = 2
⇒ 90/x - 72/x = 2
⇒ 18/x = 2
⇒ x = 9
So the actual price = 5x = 5 × 9 = 45
