Q37:

Of the families in City X in 1994, 40 percent owned a personal computer. The number of families in City X owning a computer in 1998 was 30 percent greater than it was in 1994, and the total number of families in City X was 4 percent greater in 1998 than it was in 1994. What percent of the families in City X owned a personal computer in 1998?

A. 50%

B. 52%

C. 56%

D. 70%

E. 74%

1994 = 40 families (40% of total)

1998 = 40 F * 30% = 12+40 = 52 families.

Population in 1994 = 100; 1998 = 104

==> 52/104 = 1/2 = 50%
