If the thousands digit is even, examine the number formed by the last three digits must be divisible by 16.
i.e 254,176: 176.
If the thousands digit is odd, the number formed by the last three digits plus 8 must be divisible by 16.
i.e 3408: 408 + 8 = 416.
i.e 254,176: 176.
If the thousands digit is odd, the number formed by the last three digits plus 8 must be divisible by 16.
i.e 3408: 408 + 8 = 416.

@All
(935421 x 625) = (935421 x 5^4)
Because 5 x 5 x 5 x 5 = 5 ^4 = 625.
= {935421 x (10 /2)4},
= {935421 x 100000 /16},
= {93542100000/16}.
Than only simple division on your method.

By using the digital sum method you simply solve that question 935421*625 = ?.
Digital sum of 935421 = 6.
And the digital sum of 625 = 4.
Multiply both digital sums of 935421 and 625 because in the question we have a multiplication symbol then 6*4 is 24 digital sum of 24 is 6.
So, verify in the options there is option B is having digital is 6.
