A student determined Young's Modulus of elasticity using the formula $Y = \frac{M g L^{3}}{4 {bd}^{3} δ} .$ The value of $g$ is taken to be $9.8 m s^{- 2}$ without any significant error, his observations are as following.

Physical Quantity	Least count of the Equipment used for measurement	Observed Value
Mass $(M)$	$1 g$	$2 kg$
Length of bar $(L)$	$1 mm$	$1 m$
Breadth of bar $(b)$	$0.1 mm$	$4 cm$
Thickness of bar $(d)$	$0.01 mm$	$0.4 cm$
Depression $(δ)$	$0.01 mm$	$5 mm$

Then the fractional error in the measurement of $Y$ is :
