A \( 20 \mathrm{~cm} \) length of a certain solution causes right handed rotation of \( 38^{\circ} \). A \( 30 \mathrm{~cm} \) length of another solution causes left
\( \mathrm{P} \) handed rotation of \( 24^{\circ} \). The optical rotation caused by \( 30 \mathrm{~cm} \)

W length of a mixture of the above solutions in the volume ratio \( 1: 2 \) is :
(A) Left handed rotation of \( 14^{\circ} \)
(B) Right handed rotation of \( 14^{\circ} \)
(C) Left handed rotation of \( 3^{\circ} \)
(D) Right handed rotation of \( 3^{\circ} \)
