Question

Construct index number of industrial production from the following data:

Item	Units	Production or Output		Weight
		Base year	Current Year
Mechanical Sugar and Tea Textile Mining Transportation Electricity and Electronics	Mill. Nos. Th. Tonnes Mill. Mtrs. Th. Tonnes Mill. Nos. Mill. Nos.	237 62 572 165 335 87	400 150 820 200 727 323	5 10 35 15 20 15

Answer 1

Item	Base year (q0)	Current year (q1)	Relatives values$R=\frac{\left(q_1\right)}{\left(q_0\right)}\times 100$	Weight (W)	WR
Mechanical	237	400	168.78	5	843.85
Sugar and Tea	62	150	241.19	10	2419.35
Textile	572	820	143.35	35	5017.48
Mining	165	200	121.21	15	1818.15
Transportation	335	727	217.01	20	4340.2
Electricity and electronics	87	323	371.26	15	5568.9
				∑W = 100	∑RW = 20008.3

Index number of Industrial Production
$$\begin{gathered} \mathrm{IIP}=\frac{\sum RW}{\sum W} \\ \mathrm{or},\mathrm{IIP}=\frac{20008.3}{100}=200.08 \end{gathered}$$
