it's a refresher. Will upload solution soon

(1) \(x > 1.7 or x = 1.7\)

INSUFFICIENT as we dont know y

(2) \(y > 1.9\)

dont know x HENCE insufficient.

combining

least value of \(x=1.7\)least value of \(y\) will be \(>\) than \(1.9\)

therefore \(x+y> 3.6\)

hence sufficient

hence C

Correct me if I am wrong but

if x>1.7 and

Is x+y equal to 3.6 ?

(1) x > 1.7 or x = 1.7

(2) y > 1.9

If x can be greater than 1.7 then x can be 2.0

if y is greater than 1.9 then y can be 2.0 too

x+y can equal 4

The question is asking if x+y is equal to 3.6, in this case it is not, it is greater than 3.6
