The answer is A - 50%

Say a 100 families existed in 1994 then the number of families owning a computer in 1994 - 40
Number of families owning computer in 1998 = 40 * 130/100 = 52
Number of families in 1998 = 104

The percentage = 52/104 * 100 = 50%.

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%

Using Smart Numbers is a good technique for this problem.

After calculating the percentage increase of families owning PC is 52, when you see the population go up, the percent owned in 1998 has to inversely go down.

Only answer A is below 52.
