There are seventy clerks working in a company, of which 30 are females. Also, 30 clerks are married; 24 clerks are above 25 years of age; 19 married clerks are above 25 years, of which 7 are males; 12 males are above 25 years of age; and 15 males are married. How many bachelor girls are there and how many of these are above 25?

According to your question if it is described it would be

Total clerk = 70, Male = 40, Female = 30,
Married clerks = 30, Male = 15, Female = 15,
25 plus married clerks = 19, Male = 7, Female = 12,
25 plus clerks = 24, Male = 12, Female = 12,
25 plus unmarried clerks = 5, Male = 5, Female = 0
so Bachelor girls = 15

And none of them are above 25 years
