Question

addition of three successive multiples of 9 is 81 find out multiples​

Answer 1

Answer:

18, 27, 36.

Step-by-step explanation:

let the no.s be 9x, 9(x+1), 9(x+2).

9x+9x+9+9x+18 = 81

27x+27 = 81

27x = 54

x = 2

So, the multiples are,18, 27,36

Answer 2

Answer:

let the sum of  three successive multiples of 9 be x+x+9+x+18

Step-by-step explanation:

x+x+9+x+18=81

3x+27=81

3x=81-27

3x=54

x=54/3

x=18

so,the three successive multiples of 9 are:x=18  ;  x+9=18+9=27   ;  x+18=18+18=36
