Option 4 : 150%

Given:

Calculation:

Let the number of men, women and children who went on Sunday be 8x, 7x, 5x respectively.

Let the number of men, women and children who went on Monday be 2y, 2y, y respectively.

∴ According to question

8x – 2y = 1200

⇒ 4x – y = 600     ----(i)

5x – y = 850      ---- (ii)

∴ Solving (i) and (ii)

x = 250, y = 400

Number of men, women and children who went on Sunday = 8x + 7x + 5x = 20x = 20 × 250 = 5000

Number of men, women and children who went on Monday = 2y + 2y + y = 5y = 5 × 400 = 2000

∴ Required percentage = {(5000 – 2000)/2000} × 100 = 150%

Answer the question after reading the following passage: The traditional! approach to parenthood is completely unsatisfactory. Women have to spend many hours in child-rearing. Those with professional skills may sacrifice their career in all respects for the benefit of only one child. Because women spend time caring for their children, the services cf many expensively trained teachers, nurses, doctors and other professionals are altogether lost to society. Even if child-rearing is shared by the father, it simply means that two people waste time on an unproductive task for which they may be entirely ill-equipped. Society would be much better served if parenthood was made the responsibility of well-trained professional parents who would lock after groups of children as a paid occupation. This would end amateur childrearing and allow the biological parents to fully develop their careers for the benefit of society. Critics may argue that children rested in this would feel rejected, at least to some extent, by their natural parents. This is quite untrue. Evidence from societies where collective childrearing is practised shows that children merely experience minor upsets and are hardly affected by the separation. What is the function of expressions like ‘completely, in all respects, altogether, simply, entirety, Much, at least to some extent, quite, merely and hardly" in the passage?
