A typist uses a paper 12" by 5" length wise and leaves a margin of 1" at the top and the bottom and a margin of ½" on either side. What fractional part of the paper is available to him for typing ?  Answers:
A) 2⁄3
B) 1⁄2
C) 1⁄3
D) 5⁄7
E) None of these
Area of paper = 12 × 5 = 60 sq. inch   Area of typing part = (12 - 1 × 2) × (5 - 1⁄2 × 2)   = (12 – 2) × (5 – 1) = (10 × 4) sq. inch   ∴ Required fraction = 40⁄60 = 2⁄3   2⁄3nswer 2⁄3
