Consider the table below on the quantities of commodities alongside their prices in the year 2020 and 2022.
| Commodity | Prices(Rs.) | Quantities | ||
| In 2020 Year | In 2022 Year | In 2020 Year | In 2022 Year | |
| A | 1 | 2 | 5 | 6 |
| B | 3 | 4 | 3 | 4 |
| C | 5 | 6 | 2 | 5 |
| D | 4 | 5 | 1 | 3 |
| E | 3 | 4 | 4 | 6 |
The value of \(\sum p_1 q_0\) is :
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 55
2020 is the base year (subscript 0) and 2022 the current year (subscript 1). So \(\sum p_1 q_0\) multiplies each 2022 price by the 2020 quantity:
A: \(2 \times 5 = 10\)
B: \(4 \times 3 = 12\)
C: \(6 \times 2 = 12\)
D: \(5 \times 1 = 5\)
E: \(4 \times 4 = 16\)
\(\sum p_1 q_0 = 10 + 12 + 12 + 5 + 16 = 55\)
