Question

The sum of two natural no. Is 25 and their difference is 7 find the no. S

Answer 1

let the two natural no. were x and y

atq..............  x+y=25....................{1}
atq..............    x-y=7....................{2}
                ------------------
                  2x=32
                   x=16
putting the value of x in {2} we get
                16-y=7
                 y=9
hence the two no. are 16 and 9
