ELEMENTARY MATH

Question

I am thinking of 3-digit number.

It can be formed by using three of the digits shown on the cards below.

The digit in the tens place is 1 more than the digit in the ones place.

The digit in the tens place is 2 less than the digit the hundreds place.

Digit in the cards is 6 1 3 9 8 5

Answer 1

Answer is 865

lets say ones place is X

so that makes tens place X+1

question says tens place is 2 less than hundreds place, so that means hundreds place is 2 more than tens place

so that makes it (x+1) + 2

Now that is (X+1) + 2 X+1 X

so now lets pick X value as 5 from the digits in the cards.

now that is

8 6 5
