# What two digit number is three times the sum of its digits?

# What 2 digit number is 3 times the sum of its digits?

27 2+7=9 9x3=27

# What is the greatest three digit number whose digits have a sum of twelve?

Nine hundred thirty (930) is the highest three digit number whose digits have a sum of 12. 9+3+0=12. Any numbers higher than that will give you an sum greater than 12.

# What two two digit numbers make the sum of 83?

40 and 43, among others.

# Number that is 2 times the sum of its digits?

18 1+8=9 9x2=18

# A two digit number has the property that the sum of the number and its digits is 63 what is the original number?

54 seems to fit (54 + 5 + 4 = 63).

# Three digit number whose digit product equals the digit sum?

1+2+3=6 1x2x3=6 123

# A two digit number is 3 times the sum of each digit If 45 is added to number the digits are reversed Find the number.?

100000 2847239582

# What number is six times the sum of its digits?

that doesn't make a whole lot of sense, cuz the only digit of six is 6, so, if I'm interpreting this question correctly, the answer would just be 36. no, i actually think it…s 54.

# The sum of the digits of a two-digit number is twelve?

There are 7 possible answers: 39, 48, 57, 66, 75, 84, 93. Answer can't include a 0,1 or 2, since the other digit will need to have a value greater than 9.

# The tenths digit of a two-digit number is 3 more than the units' digit. The number is 8 more than six times the sum of the digits. Find the number.?

74 Let a1 represent the tens digit and ao represent the unit digit. From the problem, we have two equations: 10a1+ao = 8+6(a1+ao) a1=3+ao Substitute a1from the second equati…on into the first equation and solve for a0: 10(3+ao)+ao = 8+6((3+ao)+ao) 30+10ao+ao = 8+18+6ao+6ao 30+11ao = 26+12ao a0=4 Substituting this back into the second equation, we get: a1=3+4=7

# How many three digit numbers can be formed such that the sum of the digits is 6?

21 ways assuming no leading zeros, that is the smallest possible number with three digits is 100 Otherwise if leading zeros are allowed, it is 28 ways. For three digit nu…mbers the first digit can be 1-6. Leaving the remaining two digits to be 6-value_of_first_digit. For first digit 6, the remain two digits sum to 0 which means they can only be 00, ie the number 600 - 1 number For first digit 5, the remain two digits sum to 1 which means they can be 01 or 10, ie the numbers 501, 510 - 2 numbers For first digit 4, the remain two digits sum to 2 which means they can be 02. 11, 20, ie the numbers 402, 411, 420 - 3 numbers etc It can be seen that the number of ways of making a two digit number (with leading zeros) sum to a number less than 10 is the required sum plus 1. So for the remaining first digits, the number of ways are: 3 -> 4 ways, 2 -> 5 ways, 1 -> 6 ways. Thus the total number of ways is 1 + 2 + .. + 6 = 21 If leading zeros are permitted, so that, for example, 060 (60) and 006 (6) are considered as three digits numbers, then there are a further 7 ways with a first digit of 0, making a total 28 ways.
