Jane makes toy bears. When she works with an assistant, she makes 60 percent more bears per week and works 10 percent fewer hours each week. Having an assistant increases Jane’s output of toy bears per hour by what percent?	Choose the correct choice from the following:  A) 70%  B) 80%  C) 100%  D) 180%  E) 200%
We can use fractional equivalents here to solve the problem   80% = 4/5; this means that in 1st case if she prepares 5 bears, in 2nd case she prepares 9 bears   10% = 1/10; this means that in 1st case if she needs 10 hours, in 2nd case she needs 9 hours   Now we come to productivity   Based on above fractional values the productivity in 1st case is 0.5 bears / hour and in the 2nd case it is 1 bear / hour   Hence the productivity is double with the assistant i.e. the increase in productivity is 70%   70%
