Solution :
Let x , y are two numbers ,
According to the problem given ,
x + y = 97 ----( 1 )
x - y = 37 ------( 2 )
Add ( 1 ) & ( 2 ) , we get
2x = 134
=> x = 134/2
=> x = 67
substitute x = 67 in equation ( 1 ),
we get
67 + y = 97
=> y = 97 - 67
=> y = 30
Therefore ,
product of the numbers = xy
= 67 × 30
= 2010
