Explanation:

Number of non graduate (male + female) in February = 350 * 3/5 = 210

Number of non graduate (males + females) in May = 320 * (5/4)=400

Number of females (graduate + non graduate) in February = (350 +210-240)=320

Similarly in May = (320 +400-320) = 400

Required ratio = (240+320) : (320+400)= 7 : 9IncorrectAnswer –

**5) 7 : 9**
