Options:
A . 6995
B . 180
C . 1550
D . 99090
Answer: Option D Answer: (d)According to the question, First number = a = 103; Last number = l = 998 If the number of such numbers be n, then, 998 = 103 + (n – 1) × 5 (n – 1) × 5= 998 – 103 = 895 n – 1 = $895/5$ = 179n = 180S = $n/2(a+l)$=$180/2$(103 +998) = 90 × 1101 = 99090
