- A215
- B218
- C224
- D220
Solution & Step-by-step Explanation
Let the initial price of one notebook be ₹100.
Total budget available = Price×Quantity=100×253=₹25300
The new price of one notebook after a 15% increase is:
New Price=100×1.15=₹115
The number of notebooks that can be purchased with the same budget now is:
New Quantity=
New Price
Total Budget
=
115
25300
Dividing by 5:
23
5060
Dividing by 23:
23×2=46⟹
23
5060
=220
Thus, 220 notebooks can be purchased.
