To calculate the amount put back into the business, we need to determine 20% of the profit. Here's the calculation:
Total profit = Ksh 225,000
Amount put back into the business = 20% of the profit
Amount put back into the business = 0.2 * Ksh 225,000
Amount put back into the business = Ksh 45,000
Therefore, Ksh 45,000 was put back into the business.
