Given- Y/X= 3/1, Suppose k is the constant
then Y= 3K and X= K
We cant find the value of Y here. Hence statement is insufficient.
Statement 2- x+y= 80, Hence, We cant find the value of Y if we don't know the value of X. hence insufficient.
By putting together- 3k+k= 80 so K= 20
y= 3K , SO Y= 60.
Option C is correct.
