Given :-

  • Sum of the two numbers = 56

  • Difference between the two numbers = 10

To Find :-

  • Two numbers

Solution :-

Let the two numbers be 'm' and 'n'

Now we can get,

1) m + n = 56

2) m - n = 10

1) First we will solve the first equation,

m + n = 56

n = 56 - m

2) Now, solve the second equation,

m - n = 10

By substituting n = 56 - m we get,

m - (56 - m) = 10

56 - m - m = 10

56 - 2m = 10

-2m = 10 - 56

-2m = -46

m = - 46/-2

m = 23

Now, we will find 'n' by the equation 1 ,

n = 56 - m

n = 56 - 23

n = 33

Hence, The two numbers are (A) 23 and 33

Let's verify :-

33 + 23 = 56

33 - 23 = 10

Hence, verified
