Bigger one is better option
r is radius of first pumpkin and R is radius of second pumpkin
v is volume of first pumpkin and V is volume of second pumpkin

for 1st pumpkin circumfrence 2 x Pi x r = 60Cm
r = 30/Pi

for 2nd pumpkin circumfrence 2 x Pi x R = 50Cm
R = 25/Pi

Volume of 1st pumkin = v = 4/3 x Pi x (30/Pi)^3

Volume of 2nd pumkin = V = 4/3 x Pi x (25/Pi)^3

v/V = 30^3/25^3 = 1.728

v is 1.728 times V

where as price is 1.5times of second pumpkin.

so bigger option is better.
