Question

The table below gives the data of tourists visiting $5$ hill stations over two consecutive years. Study the table and answer the questions that follow:

Hill stations	Nainital	Shimla	Manali	Mussoorie	Kullu
$2008$	$4000$	$5200$	$3700$	$5800$	$3500$
$2009$	$4800$	$4500$	$4200$	$6200$	$4600$

In which hill stations was there increase in number of tourists in the year $2009 ?$

Accepted Answer

From the table of data given,

Comparing the number of tourists in Nainital in two years, we get, $4000 < 4800$ i.e. the number of tourists increased in Nainital in $2009$ .

Comparing the number of tourists in Shimla in two years, we get, $5200 > 4500$ i.e. the number of tourists decreased in Shimla in $2009$ .

Comparing the number of tourists in Manali in two years, we get, $3700 < 4200$ i.e. the number of tourists increased in Manali in $5200$ .

Comparing the number of tourists in Mussoorie in two years, we get, $5800 < 6200$ i.e. the number of tourists increased in Mussoorie in $3500$ .

Comparing the number of tourists in Kullu in two years, we get, $3500 < 4600$ i.e. the number of tourists increased in Kullu in $2009$ .

Hence, the number of tourists was increased in the year $2009$ in the hill stations Mussoorie, Kullu, Manali, and Nainital.
