Q1:

What will be the number of females above the poverty line in the State S if it is known that the population of State S is 7 million?

A 3 million

B 2.43 million

C 1.33 million

D 5.7 million

ANS:B - 2.43 million

Total population of State S = 7 million. Therefore Population above poverty line     = [(100 - 19)% of 7] million     = (81% of 7) million     = 5.67 million. And so, the number of females above poverty line in State S

    = ( 3 x 5.67 ) million
7
    = 2.43 million.
