Pizza shops make pizza of same thickess and different diamester. Cost of 8cm is 80, 12 cm is 240, 24 cm is 720.

Which pizza gives best value for money?

• in the first case cost per cm is r.s 10..in the second case its r.s 20..in the third its 30..so the 1st case is the best choice

• If we consider price per unit volume of the pizza,then volume of the pizza will be=pi*r^2*h , wher r=radius
  So,volume = A*r^2,since thickness h is constant for all and A=pi*h
  For 1st one, price per unit volume = 80/(A*4^2)=5/A
  2nd " = 240/(A*6^2)=6.67/A
  3rd " = 720/(A*12^2)=5/A
  Therefore,the 2nd one gives the best value for money.

• ans is d.
  can write in the frm of ratio like
  8/80:12/240:24/720
  =>> 36:18:32
  18 is the lowest thus it is dhe best value..
