D. Of the 1400 college teachers surveyed, 42% said that they considered engaging in research as essential goal. How many of the college teachers surveyed were women?

1. In the survey, 36% of the men and 50% of the women said that they considered engaging in research an essential goal.

2. In the survey, 288 men said that they considered engaging in research an essential goal.

Total College teachers surveyed = t = m + w = 1400

Men College teachers surveyed = m

Women College teachers surveyed = w

College teachers who were surveyed and considered engaging in research as essential goal = c = 42% of 1400 = 588

Men College teachers who were surveyed and considered engaging in research as essential goal = ms

Women College teachers who were surveyed and considered engaging in research as essential goal = ws

so, ws = ?

1: ms = 36% of m

ws = 50% of w

36% of m + 50% of w = 588. nsf..

2: In the survey, 288 men said that they considered engaging in research an essential goal.

nothing about women. nsfff..

togather: ms = 288 which is 36% of m

288 = 36% of m

m = 288/0.36% = 800

w = 600

so C. suff.

I agree to the above exp. but OA is A.

lets do it again

Men College teachers surveyed = m

Women College teachers surveyed = w

Total College teachers surveyed = t = m + w = 1400

Men College teachers surveyed = m = 1400 - w

Women College teachers surveyed = w = 1400 - m

College teachers who were surveyed and considered engaging in research as essential goal = c = 42% of 1400 = 588

Men College teachers who were surveyed and considered engaging in research as essential goal = ms

Women College teachers who were surveyed and considered engaging in research as essential goal = ws

so, ws = ?

1: ms = 36% of m

ws = 50% of w

36% of m + 50% of w = 588

36% of m + 50% of (1400 - m) = 588

36% of m + 50% of (1400 - m) = 588

m = 800 and w = 600.

suff........................

2: In the survey, 288 men said that they considered engaging in research an essential goal.

nothing about women. nsf..........................

so A. suff.
