Rs. 25 and Rs. 20
Rs. 15 and Rs. 12
Rs. 30 and Rs. 24
Rs. 10 and Rs. 8
A reduction of 20% in the price of rice enables a person to purchase 10 kg more in Rs. 600.
Calculation:
Let the price per kg was Rs. 100x and after 20% reduction new price becomes Rs. 80x
According to question,
New quantity rice – old quantity rice = 10 kg
⇒ 600/80x – 600/100x = 10
⇒ 120/80x = 10
⇒ x = 3/20
Original price = 100x = Rs. (100 × 3/20) = Rs. 15 per kg
New price = 80x = Rs. (80 × 3/20) = Rs. 12 per kg
∴ Original price and the new price are Rs. 15/kg and Rs. 12/kg respectively.

d) 45
The price of an item is reduced by 20%. As a result, customers can get 2 kg more of it for ₹360
Calculation:
20% = 1/5
Let the actual price be 5x
So, after reduction it will be 4x
According to the question,
(360/4x) - (360/5x) = 2
⇒ (90/x) - (72/x) = 2
⇒ [(90 - 72)/x] = 2
⇒ 18 = 2x
⇒ x = 9
So, actual price = 5 × 9 = 45
∴ The original price (in ₹) per kg of the item is 45.
