Peter has a box containing 65 red and blue balls. Counting them, he realizes that there is a ratio of 3 red balls to 10 blue balls. How many blue balls does he have in total?
He started out with 47 balls after winning 2 blue balls and losing 3 red balls.
What is equation?The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign. Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation.
The "=" sign and terms on both sides must always be present when writing an equation. Equal treatment should be given to each party.
Here,
Let the number of blue balls be x and the number of red balls be y,
after 5 days ,
x + 10 = y - 15
after 9 days ,
x + 18 = 2 * ( y - 27 )
subtracting both,
8 = y - 39
y = 47
The number of red balls in beginning is 47.
He had 47 balls in the beginning as he win 2 blue ball and lose 3 red balls.
Therefore, He started out with 47 balls after winning 2 blue balls and losing 3 red balls.

Write a program that reads a monetary amount in dollars and cents (such as 37.84) and computes the equivalent in bills and coins, using the largest denominations possible.
Use a Scanner object to read in a double value for the monetary amount
Convert the total monetary amount to an integer representing the total number of cents (there are 100 cents in a dollar)
US monetary denominations
ten dollar bill = 1000 cents
five dollar bill = 500 cents
one dollar bill = 100 cents
quarter coin = 25 cents
dime coin = 10 cents
nickel coin = 5 cents
penny coin = 1 cent
Use integer division (/) and modulus (%) to calculate each denomination and the cents left over
Hint: You will need to successively divide the remaining cents by the number of cents in the denomination, starting with the ten dollar bills.
tens = remainingCents / 1000; // Divide the total cents by the number of cents in $10
remainingCents = remainingCents % 1000; //Remainder of division by 1000 is what is left after $10 bills taken out
When user input appears as shown in Figure 1, your program should produce output as shown in Figure 2.
Figure 1: (input)
37.84
Figure 2: (output)
$37.84 is equivalent to the following:
3 ten dollar bills
1 five dollar bills
2 one dollar bills
3 quarters
0 dimes
1 nickels
4 pennies
import java.util.Scanner;
public class MoneyConversion
{
// This program reads a monetary amount and computes the equivalent in bills and coins
public static void main (String[] args)
{
double total;
int tens, fives, ones, quarters, dimes, nickels;
int remainingCents;
Scanner scnr = new Scanner(System.in);
// Read in the monetary amount
total = scnr.nextDouble();
// Add the remaining code to finish out the program
}
}
Using the knowledge of computational language in python we can write the code as program that reads a monetary amount in dollars and cents (such as 37.84) and computes the equivalent in bills and coins, using the largest denominations possible.
Writting the code:import java.util.Scanner;
public class Money {
public static void main(String[] args) {
double amount; // This displays user's amount
int one, five, ten;
int penny, nickel, dime, quarter;
// Create a Scanner object to read input.
Scanner kb = new Scanner(System.in);
// Get the user's amount
System.out.print("What is the amount? ");
amount = kb.nextDouble();
// Calculations
ten = (int) (amount / 10);
amount = amount % 10;
five = (int) (amount / 5);
amount = amount % 5;
one = (int) (amount / 1);
amount = amount % 1;
quarter = (int) (amount / .25);
amount = amount % .25;
dime = (int) (amount / .10);
amount = amount % .10;
nickel = (int) (amount / .05);
amount = amount % .05;
penny = (int) (amount / .01);
amount = amount % .01;
// Display the results
//println adds a new line by default
System.out.println(ten + " tens.");
System.out.println(five + " fives.");
System.out.println(one + " ones.");
System.out.println(quarter + " quarters.");
