(1) 60% of the patients are male, and the rest are female
Male = 60% = 60/100*400 = 240
Female = 400 - 240 = 160
No information about percentage from each male and female group
Insufficient
(2) 25% of the male patients are in IC, and 80% of the female patients are in the RC.
25% of M
80% of F
No information about male and female breakdown
Insufficient
Combining both:
We have information about male and female breakdown and about percentage from each male and female group
Sufficient
Hence, C.

To find what percent of the hospital's patients are in IC
A certain hospital has 400 patients
Statement 1
60% of the patients are male, and the rest are female
=> \(\frac{60}{100} * 400\) = 240 male patients and 160 female patients
We dont know anything about number of patients in IC or RC
Statement 1 is not sufficient
Statement 2
25% of the male patients are in IC, and 80% of the female patients are in the RC.
From statement 2 alone, we dont know the number of male patients or female patients
Statement 2 is not sufficient
Combining statements 1 and 2
25% of the 240 male patients are in IC => 60 male patients in IC and remaining 180 male patients are in RC
80% of the 160 female patients are in RC => 128 female patients in RC and remaining 32 female patients are in IC
% of IC patients = \(\frac{60+32}{400}\) = \(\frac{92}{400}\)
Statements 1 and 2 together are sufficient
Hence option C
