In 2009, if FT were to charge the same rate to its advertisers as TOI was charging a year ago, their cost of advertisement per thousand copies in FT would:
decrease by 50%
increase by Rs. 140
decrease by Rs. 400
increase by 25%
None of these
Solution
Advertising tariff for FT in 2008 is 14000 per page instead of 28000 per page.
$\therefore$ Cost in 2008 $= \dfrac {28000}{31} $
Cost in 2009 $= \dfrac {14000}{31}$
$\therefore$ Decrease % $= \dfrac {\frac{28000}{31} - \frac{14000}{31}}{\frac{28000}{31}} \times 100 = 50\%$
