Number of ways to arrange five different books on a shelf
= 5 ! = 5 ´ 4 ´ 3 ´ 2 ´ 1 = 120
Number of minutes in 2 hrs = 2 ´ 60 = 120
Hence C.
.2 + .2 + .2 = 0.6
.2 ´ .2 ´ .2 = .008
Hence A.
 a + a + a + a = 4a = 4 ´ ( 0.2 ) =  0.8
a ´ a ´ a ´ a = a^{4} = ( 0.2 )^{4} = + 0.0016
Hence B.
Area of rectangle = length ´ width
=157 ´ 2 = 314 cm^{2}
Area of circle = p r^{2}
= 3.1415 ......... ´ 10^{2}
= 3.1415.......... ´ 100
= 314.15 .......
Hence B.
Column A has all positive factors namely x^{2}, y, and z so that x^{2} y z is positive factors namely x^{2}, y and z so that x^{2} y z is positive. Column B has one negative factor namely x with y and z^{2} being positive so that xyz^{2} is negative.
Hence A.
1 < x < 0 means x is a negative proper fraction.
\ x^{2} will be a positive proper fraction.
i.e. x^{2} < 1 or x^{2}  1 < 0
\ I is true.
Also x^{2} being positive and x being negative x^{2} > x i.e. II is also true.
x being negative, x^{3} is also negative.
\ x^{3} + x < 0  III is false.
Hence D.
Let there be 100 students in all and let the maximum marks be also 100.
Marks obtained by 40 students = 40 ´ 60 = 2400
Marks obtained by 60 students = 60 ´ 40 = 2400
Total marks obtained by 100 students = 4800
\ Class Average
Hence C.
p + q + 27 = 180  90 p + q = 90  27 = 63
Hence E.
