Question

In a room there are some student and guavas. If each student cats four guavas, then one student is left
alone without having any guava. If each student eats three guavas, then one guava is left, Write the main
of equations to find the number of students and guavas.
​

Answer 1

$\bf\large\underline\pink{Answer:-}$

The pair of equations to find the number of students and guavas are

(x-1)*4=y

x*3=y-1

1. Lets say there are x students and y number of guavas.

2. Initially if each student eats 4 guavas then one student is left without any guava. That means x-1 students ate all the guavas. Mathematically

(x-1)*4=y

3. Now if each student eats 3 guavas then one guava is left without any student. That means x students ate all the guavas except one. Mathematically

x*3=y-1

4. Solving the two equations by replacing y by (x-1)*4 from first equation.

3x=4x-4-1

x=5

no. of students =5

y=(x-1)*4=4*4=16.

no. of guavas=16

Answer 2

Answer:

Heyaa♡♡

Here is the answer :-

The pair of equations to find the number of students and guavas are

The pair of equations to find the number of students and guavas are(x-1)*4=y

The pair of equations to find the number of students and guavas are(x-1)*4=yx*3=y-1

1. Lets say there are x students and y number of guavas.

2. Initially if each student eats 4 guavas then one student is left without any guava. That means x-1 students ate all the guavas. Mathematically

(x-1)*4=y

3. Now if each student eats 3 guavas then one guava is left without any student. That means x students ate all the guavas except one. Mathematically

x*3=y-1

4. Solving the two equations by replacing y by (x-1)*4 from first equation.3x=4x-4-1

x=5

no. of students =5

y=(x-1)*4=4*4=16.

no. of guavas=16
