var a, b, n, i: integer; // set variables of integer type

begin

for i: = 10 to 99 do // organize a loop in which we iterate over all two-digit numbers

begin

a: = i div 10; // get the first digit of a two-digit number

b: = i mod 10; // get the second digit of a two-digit number

if b> a then n: = n + i; // check if the number of ones is more than the number of tens, then add a two-digit number to the sum

end;

write (‘the sum of two-digit numbers in which the number of ones is more than tens =’, n); // display the answer to the screen
