Answer 1

Answer: (B)

24, 11

Let the two numbers be x and y.
As per question sum of two numbers is $x+y=35$......eq(1)
And their difference is $x-y=13$...................................eq(2)
On Adding equation 1 and 2 we get
$x+y=35$
$x-y=13$
____________
$2x=48$
Therefore x=24
As per equation (1) $x+y=35$
Putting the value of x we get,$24+y=35$
Therefore y=11
