We will check each calculation step by step to see if the amounts on the bill are correct.

Step 1 — Calculate Item Amount and Sub Total

First, we find the cost of the items. The bill shows 3 CFL Bulbs, each costing ₹150.00.

$\text{Amount for CFL Bulbs} = \text{Quantity} \times \text{Price per item}$

$= 3 \times ₹150.00$

$\boxed{₹450.00}$

The Sub Total is the sum of all item amounts. Since there is only one item, the Sub Total is the amount for the CFL Bulbs. The bill shows the Sub Total as ₹450.00. This calculation is correct.

Step 2 — Calculate CSST (8%)

Next, we calculate the CSST (Central Sales and Service Tax) which is 8% of the Sub Total. The Sub Total is ₹450.00.

$\text{CSST} = 8\% \text{ of Sub Total}$

$= \frac{8}{100} \times ₹450.00$

$= 0.08 \times 450$

$\boxed{₹36.00}$

The bill shows CSST 8% as ₹40.50. This calculation is incorrect.

Step 3 — Calculate SOST (8%)

Then, we calculate the SOST (State Sales and Service Tax) which is also 8% of the Sub Total. The Sub Total is ₹450.00.

$\text{SOST} = 8\% \text{ of Sub Total}$

$= \frac{8}{100} \times ₹450.00$

$= 0.08 \times 450$

$\boxed{₹36.00}$

The bill shows SOST 8% as ₹49.80. This calculation is incorrect.

Step 4 — Calculate Total Amount

Finally, we calculate the Total amount by adding the Sub Total, CSST, and SOST. We use our calculated values for CSST and SOST.

$\text{Total Amount} = \text{Sub Total} + \text{CSST} + \text{SOST}$

$= ₹450.00 + ₹36.00 + ₹36.00$

$= ₹486.00 + ₹36.00$

$\boxed{₹522.00}$

The bill shows the Total as ₹531.00. This calculation is incorrect.

Answer

The calculations in the bill are not correct. The item amount and subtotal are correct. However, the CSST 8% should be ₹36.00, not ₹40.50. The SOST 8% should be ₹36.00, not ₹49.80. The total amount should be ₹522.00, not ₹531.00.
