1.
313926/39.1%~ 320000/40 ~8K
others: cable xx: 212617/8 = 21k higher than DSL

NO



2.
Case: Total profit
Total profit: 152* 49.9%= 150*50= 7500
others: seems lower


Case : profit per subscriber
Profit per subscriber : 152
others: seems lower

YES

3. In which of the three area types(Urban, Suburban or Rural) are the most subscribers that use a certain connection type.
>> means rural use most of dial up

Case1:maximum possible
Assume urban is total in DSL and Cable xx
and 2nd highest: 1.2 % in Dial up and Mobile, fixed wirless (24.9)

Dialup( maximum possible)= 1.2%~
DSL(maximum) 39.1%
cable xx(maximum) 8.6%
Mobile xx( maximum possible)= 24.9%~

total = 73.7%( higher than 66%)

case2: minimum possible
definitely below 66% as it could be 34%(1/3rd+) for DSL and cable xx
others assume 0%
0+13~+3~+ 0% = 16% ( lower than 66%)

NO

Hi KarishmaB MartyMurray chetan2u

Just confirming my reasoning on statement-3.

It is "No" because it just says proportion of subscribers for each type but we don't know what is the size of each type. Let's say if DSL and Cable,Fibre Satellite and Other, both of which fall under "Urban" category has very large size as compared to Rural and Suburban then less than 66% might not be true.

For ex: 100k is combined size of both Urban whereas only it is only 1000 for Rural and Suburban combined, then definitely much greater than 66% of subscribers live in Urban area.

Please let me know if this is the correct reasoning.
