Question

A new computer will load 17% faster than the old computer. it took the old computer 22 seconds to load one graphic and 9 seconds to load a paragraph of text. if you are loading a document with 2 graphics and 1 paragraph, how long with it take the new computer to load?

Answer 1

Time taken by old computer to load one graphic   t1 = 22 sec
Time taken by old computer to load 1 paragraph   t2 = 9 sec

Since the new computer is 17% faster 
So
Time taken by new computer to load one graphic   T1 = 22 - 17/100 * 22
                                                                                      = 18.26 Sec
Time taken by new computer to load 2 graphics    T2 = 2 * 18.26
                                                                                     = 36.52 Sec
and
Time taken by new computer to load paragraph    T3 = 9 - 17/100 * 9
                                                                                     = 7.47 Sec
