Let's consider that number to be 'x'.. So, twice the number (2x) is 12 greater than than the half of the number. So the equation will be like, 2x=12+x/2 Solving this further, 2x=(24+x)/2 => 4x=24+x =>4x-x=24 =>3x=24 =>x=8.. So the number is "8".
The 3 in the hundreds place if the number 587,349 has a value of 300. This 300 is 1/10 the value of the number you're looking for, so if x is the number you're looking for, then
