b has to be greater than or equal to 14

d has to be greater than or equal to 13

b*d>=14*13

Only answer choice that satisfies above inequality is 625

E

Its E and here is the logic. we know that if we get remainder 13, b must be at least 14 or greater. Likewise, d must be larger than 12, e.g. 13 or more. So, b*d>13*14 or bd>182, the only answer choice greater than 182 is 196 (E)

Recall that the remainder from any division of positive integers must be less than the divisor.

Since, when a is divided by b, the remainder is 13, then b must be at least 14.

Since, when c is divided by d, the remainder is 12, then d must be at least 13.

Thus, b*d is least 14*13 = 182. We see that only 196 could be the value of b*d.

In this case, we know nothing about the value of a and c as no data is given. Such questions cannot be solved by hit and trial.
only data of b available is b>13. Thus minimum value of b is 14
only data of d available is d> 12. Thus minimum value of b is 13
b*d= 14*13
check the options, it can only be E
