चीनी की कीमत में 20% की कमी से एक व्यक्ति 200 रुपये में 5 किलोग्राम अधिक चीनी खरीद सकता है। प्रति किलोग्राम मूल कीमत क्या हैं?
Detailed Solution & Logic
Correct Answer:
Rs.10/ 10 रुपये
$20%\text{ reduction}\Rightarrow \text{new price}=80%\text{ of original}$
therefore Quantity increases in the ratio 5:4
Increase =1 part =5 kg
$\therefore \text{Original quantity}=4\times5=20\text{ kg}$
Original price per kg =$ \dfrac{200}{20}=₹10$
₹10 per kg
Correct Answer: Rs. 10 / 10 रुपये
