(1) x > 1.7 or x = 1.7
(2) y > 1.9

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

It's not clear what you are trying to say here. When we combine the statements we can say that x + y is NOT equal to 3.6, so the answer to the question is a definite NO, thus sufficient and answer is C.

Re: Is x+y equal to 3.6 ? [#permalink]
Statement 1) No info on Y...Insufficient
Statement 2) No info on X...Insufficient

Both the statement shows x+y>=3.6. Ans: C

STAT1: x ≥ 1.7 Not sufficient as we do know the value of y to find x+y

STAT2: y > 1.9 Not sufficient as we do know the value of x to find x+y

Both together, x ≥ 1.7 and y > 1.9 => Min x is 1.7 and min y is greater than 1.9 so x+y > 1.7 + 1.9 => x + y > 3.6
So, x+y is NOT equal to 3.6. So, SUFFICIENT
Answer will be C
Hope it helps!

Re: Is x+y equal to 3.6 ? [#permalink]
(1) x≥ 1.7.
No information about y. Hence, Insufficient.

(2) y>1.9
No information about x. Hence, Insufficient.

(1) & (2) together,
x≥ 1.7 & y>1.9
so, x + y > 1.7+ 1.9
=>x + y > 3.6. Sufficient.
