Answer 1

Answer:

Step-by-step explanation:

===========

SOLUTION :-

===========

Let x be the page required when report is retyped.  

Now, we can use work equivalence method;  

20*55*65 = 70*65*x;  

Or, x = (20*55*65)/(70*65);  

Or, x = 15.70 = 16 pages.  

Hence, % reduction in pages = (20-16)*100/20 = 20%
