Answer 1

Var a,b,c,d,e,f,k,m:integer;
begin
writeln('A, B:');
readln(a,b);
writeln('C, D:');
readln(c,d);
e:=a*100+b;
f:=c*100+d;
k:=e div f;
m:=e-k*f;
writeln('k = ',k);
writeln('Останется: ',m div 100,' гр ',m mod 100,' коп');
end.

Program to Calculate the Number of Pens and Remaining Money

To write a program that calculates the number of pens that can be purchased with a given amount of money and the amount of money that will be left, you can follow these steps:

1. Input the prices and the amount of money available: Prompt the user to enter the price of one pen in hryvnias (A) and kopecks (B), as well as the total amount of money available in hryvnias (C) and kopecks (D).

2. Convert the prices and the amount of money to a common unit: Convert the prices and the amount of money to a common unit, such as kopecks. Multiply the price in hryvnias (A) by 100 and add the price in kopecks (B) to get the total price in kopecks. Similarly, multiply the amount of money in hryvnias (C) by 100 and add the amount of money in kopecks (D) to get the total amount of money in kopecks.

3. Calculate the number of pens that can be purchased: Divide the total amount of money in kopecks by the total price of one pen in kopecks to calculate the maximum number of pens that can be purchased. Use integer division to get the whole number of pens.

4. Calculate the remaining money: Subtract the total price of the pens (obtained by multiplying the number of pens by the total price of one pen in kopecks) from the total amount of money in kopecks to calculate the remaining money.

5. Output the results: Display the number of pens that can be purchased and the remaining money to the user.

Here's an example of how the program could be implemented in Python:

# Step 1: Input the prices and the amount of money available
price_hryvnia = int(input("Enter the price of one pen in hryvnias: "))
price_kopeck = int(input("Enter the price of one pen in kopecks: "))
money_hryvnia = int(input("Enter the total amount of money available in hryvnias: "))
money_kopeck = int(input("Enter the total amount of money available in kopecks: "))

# Step 2: Convert the prices and the amount of money to a common unit (kopecks)
total_price = price_hryvnia * 100 + price_kopeck
total_money = money_hryvnia * 100 + money_kopeck

# Step 3: Calculate the number of pens that can be purchased
num_pens = total_money // total_price

# Step 4: Calculate the remaining money
remaining_money = total_money - (num_pens * total_price)

# Step 5: Output the results
print("Number of pens that can be purchased:", num_pens)
print("Remaining money:", remaining_money // 100, "hryvnias", remaining_money % 100, "kopecks")

Please note that this program assumes the user will enter valid input values. You may want to add error handling to handle cases where the input is not a valid integer.

I hope this helps! Let me know if you have any further questions.
