ସରଳ ସୁଧରେ, ଏକ ରାଶି 8 ବର୍ଷରେ ଦ୍ୱିଗୁଣିତ ହୁଏ। ବାର୍ଷିକ ହାର ହେଉଛି:
A8%
B12.5%
C10%
D15%
Answer & Solution
Correct answer: B. 12.5%
1. ଦ୍ୱିଗୁଣିତ ହେବାର ଅର୍ଥ ହେଉଛି ଉପାର୍ଜିତ ସୁଧ ମୂଳ ମୂଳଧନ ସହିତ ସମାନ।
2. ମୂଳଧନକୁ 100 ଭାବରେ ନିଅନ୍ତୁ, ତେଣୁ 8 ବର୍ଷରେ ସୁଧ ମଧ୍ୟ 100 ହେବା ଆବଶ୍ୟକ।
3. ସରଳ ସୁଧ ଅନୁଯାୟୀ 100 x R x 8 / 100 = 100 ମିଳେ।
4. ତେଣୁ 8R = 100, ଯାହା R = 12.5 ଦିଏ।
5. ହାର ହେଉଛି ବାର୍ଷିକ 12.5 ପ୍ରତିଶତ। ଧ୍ୟାନ ଦିଅନ୍ତୁ ଯେ ଏହା କେବଳ ସରଳ ସୁଧ ପାଇଁ କାର୍ଯ୍ୟ କରେ; ଚକ୍ରବୃଦ୍ଧି ଅଧୀନରେ ଏହି ରାଶି ଆହୁରି ଶୀଘ୍ର ଦ୍ୱିଗୁଣିତ ହୋଇଥାନ୍ତା।
