Answer 3

Problem 1: Number of Pencils in the Box

Let's solve the first problem step by step.

Given: - The number of pencils left in the box is 12. - The number of pencils taken out of the box is 4 times less than the number left in the box.

To find the total number of pencils in the box, we need to determine the number of pencils taken out.

Let's assume the number of pencils taken out is x.

According to the problem, the number of pencils left in the box is 4 times greater than the number taken out. So we can write the equation:

12 = 4x

To find x, we can divide both sides of the equation by 4:

12/4 = x 3 = x

Therefore, the number of pencils taken out is 3.

To find the total number of pencils in the box, we can add the number taken out to the number left in the box:

Total number of pencils = Number of pencils left + Number of pencils taken out Total number of pencils = 12 + 3 Total number of pencils = 15

So, there were 15 pencils in the box initially.

Problem 2: Total Number of Pastries in the School Cafeteria

Let's solve the second problem step by step.

Given: - The number of pastries with meat in the school cafeteria is 60. - The number of pastries with jam is 20 more than the number with meat.

To find the total number of pastries in the school cafeteria, we need to determine the number of pastries with jam.

Let's assume the number of pastries with jam is y.

According to the problem, the number of pastries with jam is 20 more than the number with meat. So we can write the equation:

y = 60 + 20

Simplifying the equation:

y = 80

Therefore, the number of pastries with jam is 80.

To find the total number of pastries in the school cafeteria, we can add the number with meat to the number with jam:

Total number of pastries = Number of pastries with meat + Number of pastries with jam Total number of pastries = 60 + 80 Total number of pastries = 140

So, there are 140 pastries in the school cafeteria in total.
