A) 15000
B) 15025
C) 15050
D) 25000
Correct Answer: C
Solution :
101+102+103+....+300 = (100+1) + (100 + 2) + (100 + 3) + ...+ (100+100) Thus, it consists of 100 terms. = (100 + 100 + 100 + ...100 times) + (1+ 2 + 3 +...+100) \[=(100\times 100)\] + (1 + 2 + 3 + .... + 100) = (10000) + (1 + 2 + 3 + ....+ 100) \[=10000+\frac{100\times (100+1)}{2}\] =10000+ 5050=15050You need to login to perform this action.
