The total sum consumer spends on cloth in 2022?

To find the Consumer Price Index (CPI), we compare the cost of a specific "basket" of goods in the current year to the cost of that same basket in a base year.

1. Calculate the Cost of the Basket in 2022 (Base Year)

In 2022, the consumer buys 90 kg of wheat at Rs 10 and 5 pieces of cloth at Rs 100.

• Wheat: $90 \times 10 = 900$
• Cloth: $5 \times 100 = 500$
• Total Cost (2022): $900 + 500 = \text{Rs } 1,400$

2. Calculate the Cost of the Basket in 2025 (Current Year)

In 2025, the prices rise to Rs 15 for wheat and Rs 120 for cloth.

• Wheat: $90 \times 15 = 1,350$
• Cloth: $5 \times 120 = 600$
• Total Cost (2025): $1,350 + 600 = \text{Rs } 1,950$

3. Calculate the CPI

The formula for CPI is:

$\text{CPI} = \left( \frac{\text{Cost of basket in current year}}{\text{Cost of basket in base year}} \right) \times 100$

$\text{CPI} = \left( \frac{1,950}{1,400} \right) \times 100$

$\text{CPI} = 1.392857 \times 100$

$\text{CPI} \approx \mathbf{139.29}$

Correct Option: 139.29 (approximately).
