And give me thanksTotal surface area of a cylinder of Radius "R" and height "h" =2πR(R+h)
Radius of the base of the cylinder =
2
28
=14 cm
Hence, total surface area of the cylinder =2×
7
22
×14(14+20)
=2992cm
2Find the height of the cylinder if the surface
area is 1,097 m² and the radius of the base is
82 mLet cost of manufacturer = Rs.100
Selling price of manufacurer to whole-saler = 100 + 18 = Rs.118
Selling price of whole-saler to retailer = 118 + [ 118 × (20/100) ] = Rs. 141.60
Selling price of retailer to customer = Rs. 141.60 + [ 141.60×(25/100) ] = Rs. 177
Hence from manufacurer to customer, the increase in cost 77%
If buying price of customer is Rs. 30.09, then cost of manufacturer = 30.09×(100/177) = Rs.17A manufacturer sells an article to a wholesaler at a profit of 18%, the wholesaler sells it to a retailers
a profit of 20%. The retailer sells it to a customer at a profit of 25%. If the customer pays 30.09 for
find the cost of the manufacturer
