Study the following pie-chart and the table and answer the question based on them.
The proportion of the population of seven villages in$1997$

 

Village	% of Population below poverty line
X	$38$
Y	$52$
Z	$42$
R	$51$
S	$49$
T	$46$
V	$58$

If in $1999$, the population of village R increases by $10\%$ while that of village Z reduces by $5\%$ compared to that in $1997$ and the percentage of population below poverty line remains unchanged for all the villages, then find the approximate ratio of population of village R below poverty line to the ratio of population of village Z below poverty line for the year $1999$.
