Which of the following numbers is not divisible by 36?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 3376.
The number which is divisible by 36 must be divisible by 4 and 9
Divisibility rule of 4: A number is divisible by 4 if the last two digits of the number are divisible by 4
Divisibility rule of 9: A number is divisible by 9 if the sum of its digits is divisible by 9
Hence,
Option 1: 3376
Last two digits = 76/4 = 19 [divisible by 4]
Sum of digits = 3 + 3 + 7 + 6 = 19 [not divisible by 9]
Thus, 3376 is not divisible by 36
