Question

The sum of 3 consecutive multiples of 8 is 729 Find these multiples

Answer 1

Let first multiple of 9 is x

so next two multiples are , x+9 and x+18

according to given condition ,

x + x+9 + x+18 = 729

3 x + 27 = 729

3 x = 702

x = 234

so first multiple of 9 = 234

next multiples are , 234 + 9 = 243

and 234 + 18 = 252
