| 115 | Trousers | L | Brown | 1500.50 |
| 116 | Ladies Top | L | Pink | 1200.25 |
Write SQL queries using SQL functions to perform the following operations:
(i) Display the name and price after rounding off to one decimal place.
(ii) Display all Gname in upper case.
(iii) Display the last three characters from Gname.
(iv) Display the highest Gcode from the table GARMENT.
(v) Display the sum of all prices of size 'L'.
