Explanation

Odd number means طاق عدد

Explanation

Suppose first digit = A

Second digit = B

A + B = 30 i

A - B = 8 ii

A = 30 - B

(30-B) - B = 8

30 - 2B = 8

-2b = 8 -22

2b = 22

B= 11 

A + 11 = 30

A = 30 - 11

A = 19

A = 19 anf B = 11

A + B = 209

Explanation

Let's have R be Najma's age.

R

And we have a younger sister who is 6 years younger than Najma:

R−6

In 10 years, the sum of their ages will be 50. So in 10 years Najma will be:

R+10

and her sister will be

R−6+10

and the two added together will be 50:

(R+10)+(R−6+10)=50

How old are they now?

(R+10)+(R−6+10)=50

2R+14=50

2R=36

R=18

and her sister is

R−6=18−6=12

Explanation

1/3​[18−8+98]

=1/3[108

=36

Explanation

More details about this question will be shared soon

Explanation

4+5+0+10+8+3=30/6

=5

Explanation

As we know that the smallest 1 digit number is 0. So its combination also will be smallest.

So smallest 9 digit number will be 100000000.

Explanation

Mode means a repeated figure.

Explanation

0.26 + 100 = 100.26
