The difference between the simple interest received from two different sources in 1500 for 3 years is 13.50. The difference between their rates of interesty is: (1500 की धनराशि पर 3 वर्षो का दो विभिन स्रोतो बियाज दर का अंतर 13.50 है तो उनकी बियाज दर का अंतर बताइए|)

Options

A. 0.001
B. 0.002
C. 0.003
D. 0.004

Explanation

(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%
