allery2 ବର୍ଷ ପାଇଁ ବାର୍ଷିକ 10% ହାରରେ 10,000 ପାଇଁ, ଚକ୍ରବୃଦ୍ଧି ସୁଧ ସରଳ ସୁଧଠାରୁ କେତେ ଅଧିକ ହୁଏ:
A100
B50
C150
D200
Answer & Solution
Correct answer: A. 100
1. ସରଳ ସୁଧ ହେଉଛି 10000 x 10 / 100 x 2 = 2000.
2. ଚକ୍ରବୃଦ୍ଧି ସୁଧ ପାଇଁ, ପ୍ରଥମ ବର୍ଷ 1000 ଦିଏ ଏବଂ ସୁଧମୂଳ 11000 ହୁଏ।
3. ଦ୍ୱିତୀୟ ବର୍ଷ 11000 ର 10 ପ୍ରତିଶତ = 1100 ଦିଏ, ତେଣୁ ଚକ୍ରବୃଦ୍ଧି ସୁଧ ମୋଟ 2100 ହୁଏ।
4. ପାର୍ଥକ୍ୟ ହେଉଛି 2100 - 2000 = 100.
5. ଏହା ମାନକ ଦୁଇ ବର୍ଷର ଫଳାଫଳ ସହିତ ମେଳ ଖାଉଛି, P x R^2 / 100^2 = 10000 x 100 / 10000 = 100.
