Answer 1

Problem Analysis

To solve this problem, we need to determine the number of candies that will be left with Petya after he and his two friends, Misha and Kati, divide their candies equally. We are given that Petya has 27 more candies than Misha and 18 more candies than Kati.

Solution

Let's assume that the number of candies Petya has is represented by P, the number of candies Misha has is represented by M, and the number of candies Kati has is represented by K.

We are given that Petya has 27 more candies than Misha, so we can write the equation: P = M + 27 We are also given that Petya has 18 more candies than Kati, so we can write the equation: P = K + 18 To find the number of candies that will be left with Petya after they divide their candies equally, we need to find the common number of candies they will have after dividing.

Let's assume that the common number of candies they will have after dividing is represented by C.

According to the problem, they will divide their candies equally, so we can write the equation: P - C = M - C = K - C Now, let's solve the system of equations to find the value of C.

Substituting the values of P from equations and we get: M + 27 - C = M - C + 18

Simplifying the equation, we get: 27 = 18

Since this equation is not true, it means that there is no common number of candies they will have after dividing. Therefore, we cannot determine the number of candies that will be left with Petya.

Conclusion

Based on the given information, we cannot determine the number of candies that will be left with Petya after he and his friends divide their candies equally.
