Answer 1

Average of First 10 odd numbers


$= \frac{1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19}{10} \\ \\ = \frac{100}{10} \\ \\ = 10$
As Average = 10, Therefore she is right.

Answer 2

Answer:

yes, her answer is correct.

Step-by-step explanation:

First ten odd numbers = 1, 3, 5, 7, 9, 11, 13, 15, 17, 19

∵ average = (sum of all given numbers)/(total numbers)

Average of first ten odd numbers = $\frac{1+3+5+7+9+11+13+15+17+19}{10}$

∴ Average of first ten odd numbers = $\frac{100}{10}$ = $10$

According to Pratyusha average of first 10 odd numbers  = 10,

Therefore she is right.
