Find the consumer index number for the year 2010 using year 2000 as the base year by using method of weighted aggregates:
| Commodity | A | B | C | D | E |
| 2000 Price per unit (₹) | 16 | 40 | 0.50 | 5.12 | 2 |
| 2010 Price per unit (₹) | 20 | 60 | 0.50 | 6.25 | 1.50 |
| Weights | 40 | 25 | 5 | 20 | 10 |
Answer & explanation
Correct answer: option 3
The correct answer is option (3) : 138.39
| Commodity | Base Price (₹)$p_0$ | Current price (₹) $p_1$ | Weights w | $p_1w$ | $p_0w$ |
|
A B C D E |
16 40 0.50 5.12 2 |
20 60 0.50 6.25 1.50 |
40 25 5 20 10 |
800 1500 2.5 125 15 |
640 1000 2.5 102.4 20 |
| $∑p_1w=24425$ | $∑p_0w=1764.90$ |
Hence , consumer index no. = $∑\frac{p_1w}{p_2w}×100$
$=\frac{442.5}{1764.9}×100= 138.39$
