Quote:
(1): let the number of homes with AC be "AC", and those without "no AC"
no AC = AC * 1.5
but no information regarding government owned homes. -> insufficient
(2): let the number of government homes be "GO"
AC = 4 * GO
2 unknowns -> insufficient
(Together):
since total has to be AC + no AC, we get 600 = AC + 1.5 AC -> AC = 240
and with AC = 4*GO we get 240 = 4*GO --> GO = 60 -> sufficient

There are 600 homes, and we need to find the number of government owned homes.
Statement 1:
(1) The number of homes that do not have air conditioning is 50 percent more than the number of homes that do.
Homes without AC = (3/2)* Homes with AC.
The ratio of Homes without AC : Homes with AC = 3x : 2x.
since, we don’t have any info about government owned homes. Insufficient
Statement 2:
(2) The number of homes that have air conditioning is four times the number of government owned homes.
Homes with AC = 4* Number of government owned homes.
since, we don’t have any info about Homes with AC. Insufficient
Combining both the statements, we get
ratio of Homes without AC : Homes with AC = 3x : 2x.
we know that 5x = 600, which means x=120.
Homes with AC = 4* Number of government owned homes.
2x = 4 * Number of government owned homes.
number of government owned homes = (x/2).
= (120/2)
= 60.
Hence, Sufficient
Option C
