Answer & explanation
Correct answer: option 3
Let the wages of each men and women be (x +50) and x respectively.
Using mixtures and allegations,

According to the question,
(x - 450) : (400 - x) = 700 : 300
⇒ (x - 450) : (400 - x) = 7 : 3
⇒ 3x - 1350 = 2800 - 7x
⇒ 10x = 4150
⇒ x = 415
Therefore, the daily wage of the women is Rs. 415.
