Solution :-
Let the 1st number be = x
Let the 2nd number be = y
Therefore, according to the question :-
x + y = 356....(i)
x - y = 120.....(ii)
Change the signs of both the equations : (i) and (ii), we get :
2 y = 476
y = 476 / 2
y = 238
To find the value of x , we simply take up the (i) equation
x + 238 = 356
x = 356 - 238
x = 118
Therefore : x = 118 and y = 238 (answer)
