Dell
computer has two branches: one in ohio and second in texas: The total no. of
employees in ohio office grew this year by 25% to 750 but the ratio of male to

the ohio office was 20% less than that of texas office.
The
total no of female employees this year in both the office is:
Solution:
Ohio texas
Last year: 600<-(2:1) (5:6)-> texas
(M:F) (M:F)
This year :
750<-(2:1) unknown ->
1200
Since we don’t know the
number of female employees in the texas office this year so we cant determine
The
total no of employees in both the offices last year was:
Solution:
1100 + 600 = 1700
A
shepherd had n goats in the year 2000. In 2001 the no of goats increased by

1000à
1400 à
980 à
1274à
1146.6
Thus the % increase =
1146.6 -1000/1000 x 100 = 14.66%
