Let's reevaluate the problem given that the price of one pen is known to be ₹ 2.25.

Let:

• $e$ be the price of one eraser.
• $p$ be the price of one pen.

Given:

1. The cost of 6 erasers and 2 pens is ₹ 15: $6e + 2p = 15$
2. The cost of more than 4 erasers (assuming this means 5 erasers) is ₹ 14, and pens for ₹ 9 (which means the remaining balance).

We already have: $p = 2.25$

Substituting $p = 2.25$ into the first equation: $6e + 2(2.25) = 15$ $6e + 4.5 = 15$ $6e = 15 - 4.5$ $6e = 10.5$ $e = \frac{10.5}{6}$ $e = 1.75$

So, the price of one eraser is ₹ 1.75, and the price of one pen is ₹ 2.25.

Summary:

• Price of one eraser ($e$): ₹ 1.75
• Price of one pen ($p$): ₹ 2.25
