5/9 th part of the population in a village are males. If 30% of the males are married, the percentage of unmarried females in the total population is

  1. 20 2/9
  2. 27 2/9
  3. 27 7/9
  4. 29 2/9

Answer

Let the population of the village be 90.

Then, total number of males = 5/9 × 90 = 50

Total number of females = 90 - 50 = 40

Married males = 30% of 50 = 15

Married females = 15

Unmarried females = 40 - 15 = 25

Percentage of unmarried females = 25/90 × 100

= 250/9 = 27 7/9

The correct option is C.
