Solving the Riddle of the Family with Many Children

Let's solve the riddle of the family with many children who have different vegetable preferences.

Given: - 7 children love cabbage. - 6 children love carrots. - 5 children love peas. - 4 children love both cabbage and carrots. - 3 children love both cabbage and peas. - 2 children love both carrots and peas. - 1 child loves cabbage, carrots, and peas.

To find the total number of children in the family, we can use a mathematical approach to solve this riddle.

First, let's denote: - C as the number of children who love cabbage. - A as the number of children who love carrots. - P as the number of children who love peas.

We are also given that the total number of children in the family is the sum of these individual groups: C + A + P.

Now, we can form equations based on the given information: 1. C + A + P = Total number of children 2. C + A - (C ∩ A) + P - (C ∩ P) - (A ∩ P) + (C ∩ A ∩ P) = Total number of children

Using these equations, we can solve for the values of C, A, and P.

Solving the Garage Puzzle

Now, let's solve the puzzle related to the number of trucks and cars in the garage, given the total number of wheels.

Given: - Total number of vehicles: 750 - Trucks have 6 wheels each. - Cars have 4 wheels each. - Total number of wheels: 3024

Let's denote: - T as the number of trucks. - C as the number of cars.

We can form an equation based on the given information: 1. 6T + 4C = Total number of wheels 2. T + C = Total number of vehicles

Using these equations, we can solve for the values of T and C.

Let's calculate the solutions for both puzzles.
