Question

13. The difference of sum of even numbers and sum of odd numbers between 10 and 20 is a) 3 b) 6 c) 1 5 d) 4

Answer 1

Answer:

(C) 15

Step-by-step explanation:

Even numbers - Those numbers which are divisible by 2.

Example - 2,4,9370, etc.

Odd numbers - Those numbers which are not divisible by 2.

Example - 1,3,9399, etc.

Now, sum of even no. between 10 and 20

= 12+14+16+18

= 26+16+18

= 42+18

= 60

Also, sum of odd no. between 10 and 20

= 11+13+15+17+19

= 24+15+17+19

= 39+17+19

= 56+19

= 75

Therefore, we have,

=> Difference = 75 -60 = 15

Hence, correct answer is (C) 15.
