Ram gives a six-digit number, 468312, to Shyam to check the divisibility. Shyam tells Ram that the number is divisible by 57. Shyam asks Ram, “If we rearrange the digits of this number in descending order, then by which number will it always be divisible?”
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 3.
Rearranging the digits in descending order = 864321
Sum of digits = 8 + 6 + 4 + 3 + 2 + 1 = 24 (24 is divisible by 3)
Hence, the number in descending order is divisible by 3.
