If 21998 – 21997 – 21996 + 21995 = K.21995, then the value of K is
A. 1

B. 2

C. 3

D. 4

Answer :

21998 – 21997 – 21996 + 21995 = K.21995

The above question can be written as follows:



For first part,


a = 2


m = 1998


n = 1995


m – n = 1998 - 1995


= 3


For second part,


a = 2


m = 1997


n = 1995


m – n = 1997 – 1995


= 2


For third part,


a = 2


m = 1996


n = 1995


m – n = 1996 - 1995


= 1


For second part,


a = 2


m = 1995


n = 1995


m – n = 1995 – 1995


= 0




k = 8 - 4 – 2 + 1


k = 3


So the correct answer is C.
