Question

the sum of three conseccutive multiples of 3 is 225​

Answer 1

Answer:

the sum of three consecutive multiples of 3 is 81

Answer 2

Answer:

Let the three nos. be 3x, 3(x+1), and 3(x+2)

so BTP,

3x + 3(x+1) + 3(x+2) = 225

or, 9x + 9 = 225

or, 9x = 225 - 9

or, 9x = 216

or, x = 216 ÷ 9

or, x = 24

so, the three nos are 3x = 72

                                    3(x+1) = 75

                            and 3(x+2) = 78
