Verify the calculations presented in the attached document regarding mess food expenses for H Platoon, 47th Battalion PSC Ghaziabad.

• Total expenditure on regular meals for the entire month: Rs 118592
• Cost per regular meal: Rs 32
• Total expenditure on special meals: Rs 31000

The costs for individual special meals are given as Rs 160, Rs 135, and Rs 155. The stated average is Rs 150.
Let's calculate the average:

The calculated average matches the stated average.

A specific calculation is provided for a subset of meals:

• Cost for regular meals: $54 \times \text{Rs } 32 = \text{Rs } 1728$
• Cost for special meals: $3 \times \text{Rs } 150 = \text{Rs } 450$ (using the average special meal cost)

The total for this specific calculation is:

This total matches the "पूरे माह में साधारण + स्पेशल पर व्यय Rs 2178" line in the document.

The document presents two different scales of total expenditure:

1. The sum of total monthly regular and special meal expenses: $\text{Rs } 118592 + \text{Rs } 31000 = \text{Rs } 149592$.
2. A specific calculated total of $\text{Rs } 2178$ based on 54 regular meals and 3 special meals. This suggests the Rs 2178 total is for a specific subset of meals or a particular individual's contribution, rather than the overall monthly total for the entire platoon.

All calculations presented in the document are arithmetically correct based on the given numbers.
The verified calculations are:

• Average special meal cost: $\boxed{\text{Rs } 150}$
• Cost for 54 regular meals: $\boxed{\text{Rs } 1728}$
• Cost for 3 special meals: $\boxed{\text{Rs } 450}$
• Total for 54 regular and 3 special meals: $\boxed{\text{Rs } 2178}$
