To calculate the amount of money Olga Ivanovna has, we can use the information provided.

Given: - Lydia Petrovna has 3600 rubles. - 25% of this amount constitutes 45% of Olga Ivanovna's money.

Let's calculate Olga Ivanovna's money step by step.

1. Calculate 25% of Lydia Petrovna's money: - 25% of 3600 rubles = (25/100) * 3600 = 900 rubles.

2. Calculate Olga Ivanovna's total money: - 900 rubles constitutes 45% of Olga Ivanovna's money. - Let's denote Olga Ivanovna's total money as "x". - So, (45/100) * x = 900 rubles. - Solving for x, we get: x = (900 * 100) / 45 = 2000 rubles.
