area of 1st pizza=pi*7^2/4=38.5 for Rs. 70
area of 2nd pizza=pi*14^2/4=44 for Rs. 210
area of 3rd pizza=pi*21^2/4=346.5 for Rs. 610
so the bigger area gives the value for money

small pizza gives the best value for money
7cm for rs 70
14cm for rs210, which is costlier than small
21cm for rs 630, again it is costlier than small
since the question is asking for "best value for money" so small gives the best value for money as it gives more pizza in less money compared to others.

amulya cutie  (11 years ago)

area of small pizza= pi(49)
ratio of area to prize= pi(49)/70=pi(0.7)
area of medium pizza= pi(196)
ratio of area to money= pi(196)/210= pi(0.933)
area of large pizza= pi(441)
ratio of area to money= pi(441)/630= pi(0.7)

So, medium pizza has more area to money value.So its the best.

large pizza gives the best value for money since it is costely when compared to rest
7cm(cost 70rs) therefore 1cm(small pizza costs----10Rs)
14cm(cost 210rs)therefore 1cm(medium pizza costs----15Rs)
21cm(cost 630rs)therefore 1cm(large pizza costs----30Rs)
therfore the pizza which gaves best value to money is large pizza

Ans: Large pizza
consider the cost of three pizza 70,210,630
consider diameter of three pizza 7,14,21 cm
divide with the cost of each pizza by its diameter respectively
then cost of three pizza each 1cm is 70/7=10RS,210/14=15RS,630/21=30rs
Large pizza cost is greater than small and medium pizza.

dileep  (11 years ago)

both the small and large serves the best value of money because the cost is proportional to volume(weight)
volume--d^2
so the medium is not as for the satisfaction.
