Question

SOLVE IN MATLAB

11. Find the 5-digit number that satisfies the following properties: a. sum of all the digits is 23 b. sum of the first three digits is 16 c. sum of the first two digits is equal to the third digit d. third digit is twice the fourth digit e. subtracting the fourth digit from the second digit returns the fifth digit

Answer 1

Please find the code below::::

clc
clear
foundNumber=0;
for loop=10000:99999
num = loop;
digit=zeros(1,5);
for i = 1:5
digit(i) = mod(num,10);
num = floor(num/10);
end
condition1 = sum(digit)==23;
condition2 = ((digit(1)+digit(2)+digit(3))==16);
condition3 =(((digit(1)+digit(2))==digit(3)));
condition4 = digit(3)==2*digit(4);
condition5 = (digit(2)-digit(4))==digit(5);
if(condition1 &&condition2 && condition3 && condition4&& condition5)
foundNumber = loop;
break;
end
end

fprintf("The number is %d\n",foundNumber);

output:
