In a recently conducted national entrance test, boys constituted 65% of those who appeared for the test. Girls constituted the remaining candidates and they accounted for 60% of the qualified candidates.

Which one of the following is the correct logical inference based on the information provided in the above passage?

  • A.Equal number of boys and girls qualified
  • B.Equal number of boys and girls appeared for the test
  • C.The number of boys who appeared for the test is less than the number of girls who appeared
  • D.The number of boys who qualified the test is less than the number of girls who qualified

Answer: D

The correct inference is The number of boys who qualified the test is less than the number of girls who qualified.

Girls account for 60% of the qualified candidates, so boys account for the remaining 40%. Whatever the total number who qualified, 40% of it is less than 60% of it.

The other options fail. Equal numbers qualifying would need a 50:50 split, not 40:60. Boys made up 65% of those who appeared and girls 35%, so the numbers appearing were not equal, and more boys appeared than girls, which is the opposite of option C.
