What is the sum of integers 54 through 196 inclusive?
Explanation:
Sum of integers from 54 to 196 = (sum of integers from 1 to 196)– (sum of integers from 1 to 53) Sum from 1 to 196 = (196)(197)/2 = 98 × 197 = 19306
Observe that this value is already less than three out of four options. Hence, it will further decrease when the sum from 1 to 53 is subtracted from it. Hence, the answer should be less than 19306. Only 17875 satisfies this condition.
Hence, option (d).
