1. At the end of each year the value of a certain antique watch is c percent more than its value one year earlier,where c has the same value each year.If the value of the watch was k dollars on January1,1992 and m dollars on January1,1994,then in terms of m&k,what was the value of the watch, in dollars,on January 1,1995
2.The function f is defined by f(x)=-1/x for all nonzero numbers x. If f(a)=-1/2 & f(ab)=1/6, then b= ?
I am getting answer -1/3 but the bank says -3. Which one is the correct answer.
3.The toll for crossing a certain bridge is $.75 each crossing.Drivers who frequently use the bridge may instead purchase a sticker each month for $13 & then pay only $.3 each crossing during that month. If a particular driver will cross the bridge twice on each of x days next month & will not cross the bridge on any ther day, what is the least value of x for which this driver can save money by using the sticker?

Choice of answer - 1,2,4,6,8.
Working simultaneously & independently at an identical constant rate, 4 machines of a certain type can produce a total of x units of product P in 6 days. How many of these machines, working simultaneously & independently at this constant rate, can produce a total of 3x units of product P in 4 days?
Choice of answer - 24,18,16,12,8.
I have a dozen question papers with me. Answers are also provided. I am uploading them, hope it will be helpful.
