Correct Answer - Option 1 : Quantity 1 > Quantity 2
Given:
75% of female = 50% of male
66.66% of girls = 40% of boys
Calculation:
Quantity I:
Let the number of female = x and the number of male = y
⇒ 75% of x = 50% of y
⇒ 3x = 2y
⇒ x : y = 2 : 3
So, if x = number of female = 2a and y = number of boys = 3a
⇒ required % = (2a × 100) / 5a
⇒ required % = 40%
Quantity II:
Let the number of girls = x and the number of boys = y
⇒ 66.66% of x = 40% of y
⇒ 5x = 3y
⇒ x : y = 3 : 5
So, if x = number of girls = 3a then y = number of boys = 5a
⇒ required, % = 3a × 100 / 8a
⇒ required % ≈ 37%
∴ Quantity I > Quantity II
