Question : Direction: The table given below represents the production and sales of wheat in 4 different countries A, B, C, and D for 4 years. At the end of the year 2010 A, B, C, and D had a stock of 5200, 3500, 7835, and 1956 (in '000 quintals) of wheat respectively. For any given year, the stock of wheat is calculated as:
The stock of year $(n+1)$ = stock at end of year $n$ + production in year $(n+1)$ – sales in year $(n+1)$ and, Surplus of year $n$ = production in year $n$ – sales in year $n$

Wheat production and sales (in '000 quintals)
Year Country Country Country Country
2011 A B C D
Prod. Sales Prod. Sales Prod. Sales Prod. Sales
1218 1413 1881 1798 2035 2247 3126 2417
2012 1554 1783 2067 2389 1821 2018 2987 2911
2013 1671 1641 1328 2063 1937 2563 2143 3188
2014 1103 1002 1578 1239 3014 2988 4126 3563

What is the difference (in '000 quintals) in average production and average sales respectively of country C in the given four years?

Option 1: 252.25

Correct Answer: 252.25


Solution : For country C:
Total production over 4 years = 2035 + 1821 + 1937 + 3014 = 8807 ('000 quintals)
Total sales over 4 years = 2247 + 2018 + 2563 + 2988 = 9816 ('000 quintals)
The average production for country C over the 4 years = $\frac{8807}{4}$ = 2201.75 ('000 quintals)
The average sales for country C over the 4 years = $\frac{9816}{4}$ = 2454 ('000 quintals)
The difference in average production and average sales = 2454 – 2201.75 = 252.25 ('000 quintals)
Hence, the correct answer is 252.25.
