Question

85%of a no. is added to 24,the result is the same no. Find the no.?

Answer 1

Answer:

let the unknown number be x

given 85% of x + 24 = x

     x × 85/100 + 24  = x

     85x/100 + 24    = x

           17x/20 +24  = x

                     24    = x - 17x/20

                    24    = 20x/20 - 17x/20

                     24  = (20x-17x)/20

                    24  = 3x/20

       24×20     = 3x

            480  = 3x

                  160= x

hence the number is 160
