Question 1045644
(there are two no if we add 21 to first no then the ratio will be 11/4 
{{{(a+21)/b}}} = {{{11/4}}}
From the above equation we know
(a+21) = 11
and
b = 4
 what will be the ratio if we add 21 to both the nos
{{{(a+21)/(b+21)}}} = 
replace (a+21) with 11, replace b with 4
{{{11/(4+4)}}} = {{{11/8}}}
