1. A certain law firm consists of 4 senior partners and 6 junior partners. How many different groups of 3 partners can be formed in which at least one member of the group is a senior partner. 2. Pumps A, B & C operate at their respective constant rates. Pump A and B, operating simultaneously, can fill a certain tank in 6/5 hours; pumps A and C, operating simultaneously, can fill the tank in 3/2 hours; and pumps B and C, operating simultaneously, can fill the tank in 2 hours. How many hours does it take pumps A, B, and C, operating simultaneously to fill the tank. 3. Alice’s takehome pay last year was the same each month, and she saved the same fraction of her takehome pay each month. The total amount of money that she had saved at the end of the year was 3 times the amount of the portion of her monthly takehome pay that she did not save. If all the money that she saved last year was from her takehome pay, what fraction of her takehome pay did she save each month? Please Help!
