Two students appeared at an examination. One of them secured 9 marks more than the other and his marks was 56% of the sum of their marks. What are the marks obtained by them?
[ "A)42, 33", "B)44, 36", "C)44, 38", "D)45, 40" ]
A
Let the marks secured by them be x and (x + 9) Then sum of their marks = x + (x + 9) = 2x + 9 Given that (x + 9) was 56% of the sum of their marks =>(x+9) = 56/100(2x+9) =>(x+9) = 14/25(2x+9) => 25x + 225 = 28x + 126 => 3x = 99 => x = 33 Then (x + 9) = 33 + 9 = 42 Hence their marks are 33 and 42 Option 'A'

[ "A)pi^2 - 2", "B)2pi - 4", "C)4 - pi", "D)4 - pi/2" ]
B
Drawing a diagram, we see that the radius of the circle equals the side of the square. The area of intersection is: pi*r^2/4 - (r^2-pi*r^2/4) = pi*r^2/2 - r^2 = 2pi - 4 The answer is B.
