(e) 6415
(f) 9108
(g) 1728
(h) 8714
(i) 53694
(j) 40819.
Solution:
(a) 9981
First of all omit 9’s from the given number

Remaining digits of number = 8,1
Now add the remaining• digits e.
= 8, 1
8 + 1 = 9
omit this 9
Now there is no digit left’
Hence, this number is a multiple of 9
Second Method: 9981
Sum of the digits = 9 + 9 + 8 + 1 = 27

Because, sum of digits is divisible by 9
Hence, this number is a multiple of 9

(b) 6039
Sum of the digits = 6 + 0 + 3 + 9 = 18
Because sum of digits is divisible by 9

Hence, this number is multiple of 9.

(c) 243
Sum of the digits = 2 + 4 + 3 = 9

Because, sum of digits is divisible by 9
Hence, this number is a multiple of 9

(d) 6308
Sum of the digits = 6 + 3 + 0 + 8 = 17

Because sum of digits is not divisible by 9
Hence, this number is not a multiple of 9
(e) 6415
Sum of the digits = 6 + 4 + 1 + 5 = 16

Because, sum of digits is not divisible by 9
Hence, this number is not a multiple of 9

(f) 9108
Sum of the digits = 9 + 1 + 0 + 8 = 18

Because sum of digits is divisible by 9
Hence, this number is a multiple of 9

(g) 1728
Sum of the digits = 1 + 7 + 2 + 8 = 18

Because sum of digits is divisible by 9
Hence, this number is a multiple of 9

(h) 8714
Sum of the digits = 8 + 7 + 1 + 4 = 20

Because sum of digits is divisible by 9
Hence, this number is a multiple of 9

(i) 53694
Sum of the digits = 5 + 3 + 6 + 9 + 4 = 27

Because sum of digits is divisible by 9
Hence, this number is a multiple of 9

(j) 40819.
Sum of the digits = 4 + 0 + 8 + 1 + 9 = 22

Because sum of digits is not divisible by 9
Hence, this number is nòt a multiple of 9
