Answer: (c) \(\dfrac{\dfrac{\sum p_1q_0}{\sum p_0q_0} + \dfrac{\sum p_1q_1}{\sum p_0q_1}}{2}\times 100\)

Dorbish-Bowley's index is the arithmetic mean of Laspeyres' index \(\left(\dfrac{\sum p_1q_0}{\sum p_0q_0}\times 100\right)\) and Paasche's index \(\left(\dfrac{\sum p_1q_1}{\sum p_0q_1}\times 100\right)\).
