Should be C

Stmt 1 - Nos can be 10 and 20 OR 20 and 30. Products are different NOT SUFF

Stmt 2 - LCM is 180 so product can be 180, 360 NOT SUFF

together we know that product of nos = GCF*LCM. So SUFF

Hey raulverde - This is the rule of basic math. So u need not have to take care whather it is defined in official guide or not. But the stmt - product of two number = Their LCM * Their GCM - is a universal truth u can say! :wink: :D
Correct me If I am wrong


Regards,

Amitava
