Question

I am less than 1000 my one digit is 3 sum of my digit is 10 My tens digit is twice of my ones digit who am i

Answer 1

Answer:

163

Step-by-step explanation:

Let the number be abc = 100.a + 10.b + c

Given,

sum of the digits= 10 = a+b+c -------------------eq.1

Tens digit is twice of one's digit,

• b = 2.c----------------------eq.2

substituting eq.2 in eq.1,

• a+2c+c = 10
• a+3c = 10.

Given one of the digit is 3,

In this equation,

if, a=3, then c=(10/3) which is not an integer.

So, if c=3, then a = 10-(3*3) = 1.

So, a=1, b=2xc = 6, c = 3.

And the number is 163.
