Answer 1

10+10+10=30

Answer 2

$$ \Large \tt \red{Given :} $$

It is given to add any of the given three numbers to get 30...

$$ \Large \tt \green{Solution :} $$

Well, we know that,

Odd + Odd + Odd

= (Odd + Odd) + Odd

= Even + Odd

= Odd (While, 30 is even...)

We can use that as follows,

$$ \dashrightarrow $$ 15 + 13 + (11 - 9 ) = 30

$$ \dashrightarrow $$ 28 + 2 = 30

$$ \dashrightarrow $$ 30 = 30

$$ \dashrightarrow $$ LHS = RHS

$$ \implies $$ Hence, we can add 15, 13 and (11 - 9) which gives 30...
