Here are the solutions to the problems: Question 9: If 5 men can build a house in 12 days, how many men are required to build the same house in 15 days?

This means that the product of men and days remains constant (M_1 D_1 = M_2 D_2). Step 2: Substitute the given values. M_1 = 5 men, D_1 = 12 days. D_2 = 15 days. Let M_2 be the unknown number of men. 5
