If the price of a notebook decreases by 25%, then a man can buy 5 more notebooks for Rs. 200. What is the new price (in Rs) of each notebook?
Show answer & explanation
Correct answer: C
Explanation
Given:
Price reduction = 25%
₹200 buys 5 more notebooks.
Let the old price = x
New price = 0.75x
Notebooks purchased for ₹200
Old number = 200 / x
New number = 200 / (0.75x)
200 / (0.75x) = 200 / x + 5
Multiply both sides by x
200 / 0.75 = 200 + 5x
266.67 = 200 + 5x
66.67 = 5x
x ≈ 13.33
New price = 0.75x
= 0.75 × 13.33 = ₹10
