Answer» (c ) Let the rate of interest for two different sources is `r_(1) and r_(2)` respectivley (माना की दो अलग अलग स्रोतो की बियाज दर क्रमश:) According to the question( ( प्रशुनाशर). `(1500xxr_(1)xx3)/(100)-(1500xxr_(2)xx3)/(100)=13.50` `4500 r_(1)-4500r_(2)=1350` `(r_(1)-r_(2))=(1350)/(4500)=0.3%` Hence Required difference in rates (दर )=0.3% Alternnate /(तक) Let the difference in rates(माना की डरो का अंतर ) (डरो का अंतर)=d% ( तीन वर्षो में अंतर) =3d% According to the question (प्रशुनाशर)), d=`13.50/1500xx100/3=1350/4500` =0.3% |
