Question

Rohit had ‘p ‘pieces of candy.He ate 5 of them .Then he distributed the remaining pieces of candy into his 10 friends.How many pieces of Candy did each friend receive.​

Answer 1

Answer:

Let's call the number of students “ x ". Then we can say, given the amount of sweets as “ y ":

5x+13=y

8x−20=y

Multiply the top equation by 8 and the bottom by 5 to obtain:

40x+104=8y

40x−100=5y

Take the second equation from the first to give:

204=3y

y=68

Now that we have y , just substitute into one of the original equations to find x .

5x+13=68

5x=55

x=11

So there are 11 students and 68 sweets.
