    1. 4200
    2. 4410
    3. 5600
    4. 6048
Correct Option: C

Let the number of males = x
∴ Number of females= 9800 – x
According to the question,

x ×
108
+ (9800 - x) ×
105
= 10458
100100

⇒ 108 x + 9800 × 105 – 105x = 1045800
⇒ 3x + 1029000 = 1045800
⇒ 3x = 1045800 – 1029000 = 16800
⇒ x =
16800
= 5600
