Answer 1

Hey mate.

4).9991/7=1427.28

9992/7=1427.42

9993/7=1427.57

9994/7=1427.71

9995/7=1427.85

9996/7=1428

9997/7=1428.14

Sum of the total is 9985.97

So,

option is none.

Hope it will help you

Answer 2

Answer:

Step-by-step explanation:

1)the first one answer is 500

2)the second answer is

n=no of terms=1000

a=1=first term

d=difference=1

sum=n/2(2a+(n-1)d)

=500(2+999)

=500500

3)9/10 of 1000=900

8/9 of 900 =800

7/8 of 800=700

6/7 of 700=600

5/6 of 600= 500

4/5 of 500= 400

3/4 of 400=300

2/3 of 300=200

1/2 of 200=100 ans

another procedure

1/2×2/3×3/4×4/5×5/6×6/7×7/8×8/9×9/10×1000

=1/10×1000=100ans

4)none of these

9991/7+9992/7+9993/7+9994/7+9995/7+9996/7

same denominator

9991+9992+9993+9994+9995+9996=59961

divide by 7 =59961/7=8565.5
