Because 300+50+6 = 356 and 300+40+16 = 356
In 5420, you have:5 x thousand; 4 x hundred; 2 x tens; zero x ones (the American ones in math is known as units in British maths!).
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); /**/ /**/ /**/ } /**/ /**/ } /**/ } }
Ten thousands, then hundred thousands, then millions

3 hundreds, 1 ten and 2 ones.
Your correct answer is hundreds place because you have your ones period like ones tens hundreds same with the thousands period ones tens hundreds.
