A = 5m
B= 2n
C could be 1/2 and d could be 1/5

We end up with abcd= mn.. Insuff

Is the product abcd divisible by 10?

(1) a is a multiple of 5
(2) b is a multiple of 2

Target question: Is the product abcd divisible by 10?

Jump straight too.....
Statements 1 and 2 combined
There are several values that satisfy BOTH statements. Here are two:
Case a: a = 5, b = 2, c = 1 and d = 1. Here, abcd = 10. So, in this case, the product abcd IS divisible by 10
Case b: a = 5, b = 2, c = 0.3 and d = 1. Here, abcd = 3. So, in this case, the product abcd NOT divisible by 10
Since we cannot answer the target question with certainty, the COMBINED statements are NOT SUFFICIENT

Answer:
Cheers,
Brent
