3 to 40Math brain teasers require computations to solve.
I am thinking of an even number. The ratio of the sum of its digits to the product of its digits is 3 to 40 . The number is divisible by (40-3) .
What is the smallest number that meets these requirements??
HintSum of the digits = 18
Product of the digits = 240
Answer5328 is the number.
3/40 = 18/240
S.O.D. = 18; P.O.D. = 240
5328 / 37 = 144
