Answer:
362
Step-by-step explanation:
let the digits that make up the number be a, b and c with a in the hundred position, b in the tens and c in the units position. Given that
he hundreds digit is one more than the ones digit
a = c + 1
c = a - 1
and the tens digit is twice the hundreds digit
b = 2a
If the sum of the digits is 11
a + b + c = 11
substituting
a + 2a + a - 1 = 11
4a - 1 = 11
4a = 11 + 1
4a = 12
a = 12/4
= 3
recall that
c = a - 1 = 3 - 1 = 2
b = 2a = 2 * 3 = 6
Hence the number is 362
