Answer 3

Solution without an Equation

To solve this problem without using an equation, we can use a simple logical approach.

Given: - Natasha and Kati together have 27 rubles. - Kati has 3 rubles less than Natasha.

Calculation

Let's use the information provided to calculate the amount of money Kati has: - If Natasha has x rubles, then Kati has (x - 3) rubles. - According to the given information, the total amount they have together is 27 rubles.

So, we can set up the following equation: - x + (x - 3) = 27

Now, we can solve for x to find the amount Natasha has, and then calculate the amount Kati has.

Calculation Result

Natasha's amount (x): - x + (x - 3) = 27 - 2x - 3 = 27 - 2x = 27 + 3 - 2x = 30 - x = 15

Kati's amount (x - 3): - Kati has 15 - 3 = 12 rubles.

So, Kati has 12 rubles.
