There are two schemes in Vodafone
mobiles.
First scheme :1 paise per second,
Second scheme :50 paise per
minute,
Following conditions are given - 1) In second scheme, second minute
will be started at 0:60 or 1:00,
2) 0 sec. call means to call and cut it
abruptly when timer reads 0:00,
this is equivalent to a call of 1 sec.
3) In first scheme 0:14 means 15 sec.
The probability that first scheme is
more profitable over second in a
call ranging from 0:00 (1 sec.) to
3:20 (201 sec.) is ? For all a,b,c,d>0 a+b+c+d=4
prove (1/a^2) + (1/b^2) + (1/c^2) + (1/d^2) ≥ a^2 + b^2 + c^2 +d^2
