Question

My number is a multiple of 150. 9 is a factor of my number. My number has 3 digits. The sum of the digits in my number is 9 ?

Answer 1

Three digits: 100 to 999,
But multiple of 150: 150, 300,450,600,750,900
But 9 is factor: 450,900
And sum of digits is 9, both 450 and 900 satisfy. So this information prove additional.

450 and 900.

Answer 2

The three digit numbers which are multiples of 150 and having 9 as factor are only

450, 900,

In both the numbers , digits add up to 9.

So the answer is either 450 or 900

Answer 3

450 = 150*3 fulfills all the conditions.
9 is a factor of 450 since 50*9 = 450.
900 is another possibility. 900 = 150*6.

Answer 4

If htu is the number

h+t+u=9
htu/9=x (some number)
htu/150=y (some number)

1350:

1+3+5+0=9
1350/9=150
1350/150=9

Answer 5

let number be 100x + 10y + z
as number is multiple of 150, z = 0
as sum of digits = 9, x + y = 9
number may be
180, 270, 360, 450, 540, 630, 720, 810, 900
as 450, 900 are multiple of 150 hence your number is 450 or 900.

Answer 6

450
