If the LCM of two numbers a and b is 1104 and their HCF is 4, which of the following MUST be true?
I. a * b = 4416
II. a and b are both divisible by 8
III. a : b = 48 : 23
Select:
A) I only  B) II only  C) I and III only  D) II and III only  E) I, II, and III
LCM (x,y)=1104   HCF (x,y)=4   The product of two numbers is equal to product of their LCM and HCF.   x * y =1104 * 4=

4416 so statement I only is true   Since HCF (x,y) is 4 hence maximum common number with which x and y are divisible by is 4   so statement B is false   Now the ratio between x and y may be either 48:23 or 23:48   so statement C is false   Hence answer is 1   I onlyNSWER:I only
