If sum_(n=1)^k [1/3+n/90]=21 where [x] dentes the integeral part of x, then k= (A) 84 (B) 80 (C) 85 (D) none of these

Let f(n)=[(1)/(2)+(n)/(100)] where [x] denote the integral part of x. Then the value of sum_(n=1)^(100)f(n) is

If f:(0,pi)rarr R and is given by f(x)=sum_(k=1)^(n)[1+sin((kx)/(n))] where [] denotes the integral part of x, then the range of f(x) is

Let f(n)=[1/2+n/100] where [x] denote the integral part of x. Then the value of sum_(n=1)^100f(n) is

Let f(n) = [(1)/(2) + (n)/(100)] where [n] denotes the integral part of n. Then the value of sum_(n=1)^(100) f(n) is
