30.
4 tens = 4 * 10 = 40
10 less than this = 40 - 10 = 30.
We could also think of this as 10 (which is 1 ten) less than 4 tens must equal 3 tens (30).
The ones digit is 5 less than 10 (10-5=5) The tens digit is 2 more than the ones digit (5+2=7) The entire number is less than 200. It could be either "75" or "175", but is probably "175" or they would have said that the entire number was less than 100.
9 tens = 90. 4 fewer ones than tens = 9 - 4 = 5. Therefore the answer is 95.
The prime numbers between 25 and 50 are : 23 29 31 37 41 43 47However 2 and 4 (which appear in the tens place of 5 of these numbers) are not odd numbers.We are left with 31 and 37.The sum of digits of 37 is 10 which is not less than 10;but the sum of digits of 31 is 4 which is less than 10.So, 31 it is
According to the numerical puzzler, Digit total means adding up the digits in the number and then seeing if it is less than ten. Eg. 1111 = 1+1+1+1 = 4 and so is less than 10. 76 would be 7+6 = 13 and so would not be less than 10. Hope this helps?
10 less than 5

10 or 5
The ones digit is 5 less than 10 (10-5=5) The tens digit is 2 more than the ones digit (5+2=7) The entire number is less than 200. It could be either "75" or "175", but is probably "175" or they would have said that the entire number was less than 100.
Could be 31, 33 or 35...
9 tens = 90. 4 fewer ones than tens = 9 - 4 = 5. Therefore the answer is 95.
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); /**/ /**/ /**/ } /**/ /**/ } /**/ } }
Meaningless question.
"The hundreds and the ones are the same digit and their sum is 10" did you say ?Well then, the hundreds and ones digit are both 5.And the tens is 2 less than that, or 3.So the number is . . . . . 535
There is an infinite number of values between 40 and 50, or between 4/10 and 5/10. Try 45 in the first case, and 9/20 in the second.
200 + 150 + 19 = 369
