1.	Test the divisibility of the no. by 11:- 3178965
Answer» for a number to be divisible by 11 the sum of digits at odd place - sum of digits of even place , should be equal to multiple of 11 here the number is. 3178965 sum of odd place digits = 3+7+9+5 = 24 sum of even place digits = 1+8+6= 15 difference = 24-15 = 9 and since 9 is not a multiple of 11 so, the number is not a multiple of 11

Answer»

for a number to be divisible by 11

the sum of digits at odd place - sum of digits of even place , should be equal to multiple of 11

here the number is. 3178965 sum of odd place digits = 3+7+9+5 = 24 sum of even place digits = 1+8+6= 15

difference = 24-15 = 9 and since 9 is not a multiple of 11 so, the number is not a multiple of 11
