Ohh nice!!! Good job fellas!

Good old Python:

#!/usr/bin/env python

basic = 1000

def get_premium(age):
    if 15 < age < 20:
        return "$%.2f" % (basic + (15.0/100) * basic)
    elif 19 < age < 26:
    	return "$%.2f" % (basic + (5.0/100) * basic)
    elif age > 25:
    	return "$%.2f" % (basic - (10.0/100) * basic)
    else:
        return "*No insurance!*"
    	
num = int(raw_input("Enter number of drivers in the family: "))

for i in range(num):
    name = raw_input("Enter name: ")
    age = int(raw_input("Enter age: "))
    print "%s's premium: %s" % (name, get_premium(age))

The submissions keep coming in! Wahoo! Well done @EnergyWolf !

Why not 1.15 * basic rather than (basic + (15.0/100) * basic)?

[EnergyWolf]

I was just going by the formula for getting the percentage… didn’t really think about simplifying it. That looks a lot nicer though

A Perl version using a lookup table, and featuring the use of last

#!/usr/bin/perl
sub raw_input{ print $_[0]; $a=<>; chomp($a);return $a;}

@d = ((16,0), (20,1.15), (26,1.05), (200, .9));
$base = 1000;

$n = raw_input ("Please enter the number of driver in your family :");

for ($i = 0, $j = 1; $i < $n; $i++, $j++)
{
    $name = raw_input ("Driver $j Name : ");
    $age =  raw_input ("Driver $j Age  : ");
    die "Invalid Age" if $age > 200;

    for ($k =0; $k < $#d; $k+=2)  {last if ($age < $d[$k]);}

    print "The amount of insurance for $name: " . $base * $d[$k + 1] . "\n";
}
