The remainder when the determinant |[2014^(2014),2015^(2015),2016^(2016)],[(2017^(2017),2018^(2018),2019^(2019)],[2020^(2020),2021^(2021),2022^(2022)]| is divided by 5 is-

determinant of this matrix :((1^2016,2^2016,3^2016,...2018^2016),(2^2016,3^2016,4^2016,...2019^2016),(3^2016,4^2016,5^2016,...2020^2016),(...2018^2016,....2019^2016,2020^2016,....4035^2016))

The average of sales of a furniture shop in the years 2015, 2016, 2017, 2018 is Rs 16300, and that for years 2016, 2017, 2018, 2019 is Rs 18450. If the sales in 2019 are Rs 9200, then what are the sales in 2015?

[(2^(2020)+1)/(2^(2018)+1)] + [(3^(2020)+1)/(3^(2018)+1)] + [(4^(2020)+1)/(4^(2018)+1)] + [(5^(2020)+1)/(5^(2018)+1)] + [(6^(2020)+1)/(6^(2018)+1)]

Let [x] be the greatest integer less than or equal to x, for a real number x. Then the following sum [(2^(2020) + 1)/(2^(2018) + 1)] + [(3^(2020) + 1)/(3^(2018) + 1)] + [(4^(2020 ) + 1)/(4^(2018) + 1)] + [(5^(2020) + 1)/(5^(2018) + 1)] + [(6^(2020)+1)/(6^(2018)+1)] is

If f(x)=(x)/(x+1) ,Which of the following is/are CORRECT. (A) f(f(2020))=(2020)/(4041) (B) f(f(f(2020)))=(2020)/(8081) (C) f(f(f(f(2020))))=(2020)/(2321) (D) f(f(f(f(f(2020)))))=(2020)/(10101)

If f(x)=(x)/(x+1) ,Which of the following is/are CORRECT. (A) f(f(2020))=(2020)/(4041) (B) f(f(f(2020)))=(2020)/(8081) (C) f(f(f(f(2020))))=(2020)/(2321) (D) f(f(f(f(f(2020)))))=(2020)/(10101)

Let f(x)=(x(1-x))^(2) , the sum of f(1/2019)-f(2/2019)+f(3/2019)-f(4/2019)………..+f(2017/2019)-f(2018/2019) is

If (1)(2020)+(2)(2019)+(3)(2018)+…….+(2020)(1)=2020xx2021xxk, then the value of (k)/(100) is equal to
