41910.

Step-by-step explanation:

We can calculate this by first finding the sum for  k = 1 to 50 then subtracting the sum for k = 1 to 14.

We use the formula  (1/6)n(n+1)(2n+1)

So for 1 to 50 its 1/6 * 50* 51 * 101 = 42925

and for 1 to 14 it comes to 1/6*14*15*29 = 1015

So the answer is 41910.

answer:

option a.

step-by-step explanation:

for the calculation of e.m.i we use the formula as

where p = principal amount

r = rate of interest per month

n = number of installments

from the question the given values are

r = 0.054/12 = 0.0045

n = 20×12 = 240

p = $215000

by putting these values in the formula

so option a. is the right answer.
