(B) 50 (C) 75 (D) 100
(A) 10​

Answer 1

(d) 100 is the answer....

Answer 2

Answer:

The first 10 odd numbers are

1, 3, 5, 7, 9, 11, 13, 15, 17,19

The standard mathematical method of getting the sum of a series would be to add the first number of the series to the last number of the series and multiply the sum by one half the number in the series.

1 + 19 = 20

20 × 5 = 100 ( there are 10 odd numbers in the series, so half of them would be 5.

Thus the sum is 100
