Wire Combinations & Special Cases question from JEE Main 2024 (8 Apr, Shift 1)

Young's modulus is determined by the equation given by $\text{Y} = 49000\frac{\text{m}}{\text{l}}\,\frac{\text{dyne}}{\text{cm}^2}$ where $M$ is the mass and $l$ is the extension of wire used in the experiment. Now error in Young modules $(Y)$ is estimated by taking data from $M - l$ plot in graph paper. The smallest scale divisions are $5\text{ g}$ and $0.02\text{ cm}$ along load axis and extension axis respectively. If the value of $M$ and $l$ are $500\text{ g}$ and $2\text{ cm}$ respectively then percentage error of $Y$ is:
