Answer 2

Problem Analysis

We are given that a father bought a suit for his son for 96 rubles, which is 1/3 of his total money. After buying the suit, he bought a book and had 156 rubles left. We need to determine the cost of the book.

Solution

Let's assume the father's total money is represented by the variable M.

We are given that the father spent 1/3 of his money on the suit, which is equal to 96 rubles. We can set up the following equation to represent this information:

(1/3) * M = 96 We are also given that after buying the suit, the father had 156 rubles left. We can set up the following equation to represent this information:

M - 96 = 156 To find the cost of the book, we need to solve these two equations simultaneously.

Solving the Equations

Let's solve the equations using substitution or elimination method.

From equation we can isolate M:

(1/3) * M = 96

Multiplying both sides by 3:

M = 96 * 3

Simplifying:

M = 288 Now we can substitute the value of M into equation:

288 - 96 = 156

Simplifying:

192 = 156

Subtracting 156 from both sides:

192 - 156 = 156 - 156

Simplifying:

36 = 0

This equation is not true, which means there is no solution. It seems there is an error in the given information or calculations.

Conclusion

Based on the given information and the calculations, it appears that there is an error or inconsistency in the problem statement. The equations do not have a valid solution. It is not possible to determine the cost of the book with the given information.

Please double-check the problem statement or provide any additional information if available.
