A pure simple of $2$-chlorobutane shows rotation of PPL by ${30}^{\mathrm{o}}$ in standard conditions. When above samples is made impure by mixing its opposite form, so that the composition of the mixture become $87.5 \%$ $\mathrm{d}$-form and $12.5 \%$ $\mathrm{l}$-form, then what will be the observed rotation for the mixture.
