(ii)CGST=2.5*4800/100
=₹120
(iii)SGST=2.5*4800/100
=₹120
(iv)Total amount=4800+120+120

Answer:
Area of round pizza =πr^2 (Value of π=22/7 )
= 22/7 x (15)^2 ( As we know that radius =1/2 of diameter)
= 3.14 x 225 = 706.5
Area of Anjana’s pizza = 706.5 / 10 = 70.65
Area of square pizza = side x side
= 30 x 30
= 900
Area of Sanjana’s pizza = 900 / 12 = 75
Hence, Sanjana got a better deal = 75 - 70.65 = 4.35 (approximately 5 cm^2)
