Which of the following numbers is divisible by 81?

Correct option is A

Concept Used:

So divisible by 81

A number is divisible by 9 if the sum of its digits is divisible by 9. So divisible by 81

Solution:

Option (a): 5265

Sum of digits = 5 + 2 + 6 + 5 = 18

Since 18 is divisible by 9, 5265 is divisible by 81

Option (b): 5854

Sum of digits = 5 + 8 + 5 + 4 = 22

Since 22 is not divisible by 9, 5854 is not divisible by 9

Option (c): 4678

Sum of digits = 4 + 6 + 7 + 8 = 25

Since 25 is not divisible by 9, 4678 is not divisible by 9

Option (d): 5232

Sum of digits = 5 + 2 + 3 + 2 = 12

Since 12 is not divisible by 9, 5232 is not divisible by 9

Thus number 5265 is divisible by 9
