None of these



Number of men in the colony = 4/7 * 70 = 40.

Number of women in the colony = 3/7 * 70 = 40.

Number educated women in the colony = 1/5 * 30 = 6.

Number of uneducated women in the colony = 4/5 * 50 = 24.

Number of educated persons in the colony = 8 /35 * 70 = 16.

As 6 females are educated, remaining 10 educated persons must be men.

Number of uneducated men in the colony = 40 - 10 = 30.

Number of educated men and uneducated men are in the ratio 10 : 30 i.e., 1 : 3.
