If the product 6352 × 7A1 is divisible by 12, then the value of A is:
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 4.
Divisibility by 12 = Divisible by 3 and 4
6352 is already divisible by 4 (52 ÷ 4 = 13)
Sum of digits of 6352 = 6 + 3 + 5 + 2 = 16
Sum of digits of 7A1 = 7 + 1 + A = 8 + A
If A = 1 then 8 + A = 9 (Divisible by 3)
Hence, the smallest value of A is 1.
