I am a four digit number. My tens digit is 2 more than my ones digit. My hundreds and thousands digit are both 1 less than my ones digit. What number can i be?
452, 894. None other that I can think of

This is missing some information. You mentioned the tens digit twice and didn't mention the ten thousands digit. One possibility is 87184.
There is no four digit number where the ones is twice the tens, the hundreds is five less than the ones, and the thousands is the sum of the tens and hundreds. int ones, tens, hundreds, thousands; for (thousands=1; thousands<10; thousands++) { /**/ for (hundreds=0; hundreds<10; hundreds++) { /**/ /**/ for (tens=0; tens<10; tens++) { /**/ /**/ /**/ for (ones=0; ones<10; ones++) { /**/ /**/ /**/ /**/ if (ones != 2 * tens) break; /**/ /**/ /**/ /**/ if (hundreds != ones - 5) break; /**/ /**/ /**/ /**/ if (thousands != tens + hundreds) break; /**/ /**/ /**/ /**/ printf ("dd\n", thousands, hundreds, tens, ones); /**/ /**/ /**/ } /**/ /**/ } /**/ } }
Oh, dude, that's like a math riddle straight out of a textbook. So, let's break it down: if we have twice as many thousands as ones, that means the thousands digit has to be 8 (since 8x2=16). Then, twice as many ones as hundreds means the ones digit is 2 (since 2x2=4). And finally, twice as many hundreds as tens means the hundreds digit is 4 (since 4x2=8). So, the number is 8422. Math can be fun, right?
