(A) 40450
(B) 50500
(C) 76456
(D) 12009
Correct Option is: B
No of even numbers upto 1lkah = 50000
No of even numbers upto 1000 = 500
No of even numbers above 1000& upto 1 lakh= 49500
sum of first N even numbers = N*N
sum of even numbers above 1000 & upto 1 lakh = 50000*50000 – 500*500 = 2499750000
average of even numbers above 1000& upto 1 lakh = 2499750000/ 49500 = 50500
