   Option B
   Solution:
   People who like TV = x, then who like Phones = 120/100 × x = 1.2x
   Total sales of TV in all months = 1538 thousand
   Total sales of Phones in all months = 1538 thousand
   Sales of TV/person = 1538/x and
   Sales of Phones/person = 1538/1.2x
   So Sales of Phones/person is minimum.

    View Answer

    Option B
    Solution:
    15/100 × x = 30,000
    So total employees in company in present year, x = 200,000
    So total employees in G in present year = 10/100 × 200,000 = 20,000
    So total employees in G in next year = 110/100 × 20,000 = 22,000
    So male employees = 58/100 × 22000 = 12760
