Answer 1

curved surface area of cone = 22/7 x 52.5 x 50 = 8250 
curved surface area of cylinder = circumference of base x height 
circumference of base = 22/7 x 105 = 330 
curved surface area of cylinder = 330 x 5 = 1650 
you don't need the base area right...? 
so total surface area is 1650 + 8250 = 9900 
so total cost = 15 x 9900= Rs 148500
I Guess this will be right !!!!
