Solve the following following;
1.)(Inverse Variation)→ The number of days needed in repairing a house varies inversely as the number of men working.It takes 15 days for 2 min to repair the house.How many men are needed to complete the job in 6 days.
2.) (Joint variation)→The amount of gasoline used by a car varies directly as the distance travelled and square root of speed. Suppose a car used 25 liters on a 100 kilometer trip at 100 km/hr. about how many liters will use on a 192 km trip at 60 km/hr.
3.)(Direct Variation)→Every moth,a man deposits in his bank account a savings of Php 500,000.In how many months would he have saved Php120,000?

Answer:
1. The number of days needed in repairing a house varies inversely as the number of men working. It takes 15 days for 2 men to repair the house. How many men are needed to complete the job in 6 days?
• Five men are needed to complete the job in 6 days.
2. The amount of gasoline used by a car varies directly as the distance travelled and square root of speed. Suppose a car used 25 liters on a 100 kilometer trip at 100 km/hr. about how many liters will use on a 192 km trip at 60 km/hr.
1. Solve for the value of k.
2. Solve for the value of x using the given formula.
• 37.2 liters will be used on 192 km trip at 60 km/hr.
3. Every month, a man deposits in his bank account a savings of Php 500,000. In how many months would he have saved Php120,000?
