I love these: T = tens place or first digit. U = ones place, units place, or second digit. 10T+U is the first number T+U=15 = T=15-U 10U+T is the number with the digits switched. 10U+T=10T+U+9 10U+15-U=10(15-U)+U+9 9U+15=150-10U+U+9 9U+15=159-9U 18U=144 U=8 T=15-8 T=7

If the sum of a two digit number is 12 and the digits interchange their places the new number exceeds the original number by 25 what is the number?

There isn't one. The only two digit numbers whose sum of digits is 12 are: 39, 48, 57, 66. (I didn't include 75, 84, or 93 since interchanging their digits and subtracting from the original number will be a negative result.) None of the four remaining numbers will exceed the original by 25. 66 won't work since the difference will be zero. Using 39, the new number (93) will exceed the original by 54; using 48 the difference will be 36; and using 57 the difference will be 18


If the sum of a two digit number is 12 and the digits interchange their places the new number exceeds the original number by 25 what is the product?

-- "The sum of a two-digit number" is unclear. I took it to mean"The sum of the digits of a two-digit number."-- "... the product ?" is unclear. Are you looking for the product of the two digits,or the product of the forward and backward numbers ?-- It's not possible to write a number whose two digits sum to 12 and whosereverse exceeds it by 25. The tens digit would have to be 4.611... and the unitsdigit would have to be 7.388... .Then(4.611...) + (7.388...) = 12(46.111...) + (7.388...) = 53.5(73.888...) + (4.611...) = 78.5Difference = 25So, the number can't be written, but ...The product of its two digits is 34.071 (rounded)The product of the forward and reverse numbers is 4,199.75 (rounded)
