A3,200
B3,456
C4,320
D3,328
Answer & Solution
Correct answer: D. 3,328
1. ପ୍ରଥମ ବର୍ଷର ସୁଧ ହେଉଛି 20000 ର 8 ପ୍ରତିଶତ = 1600, ତେଣୁ ସୁଧମୂଳ 21600 ହୁଏ।
2. ଦ୍ୱିତୀୟ ବର୍ଷର ସୁଧ ସେହି ନୂତନ ସୁଧମୂଳ ଉପରେ ଧାର୍ଯ୍ୟ କରାଯାଏ, ମୂଳ ରାଶି ଉପରେ ନୁହେଁ।
3. ତେଣୁ ଏହା 21600 ର 8 ପ୍ରତିଶତ = 1728।
4. ମୋଟ ସୁଧ ହେଉଛି 1600 + 1728 = 3328।
5. 3200 ହେଉଛି ସରଳ ସୁଧ, ଏବଂ 128 ପାର୍ଥକ୍ୟ ହେଉଛି ଠିକ୍ ପ୍ରଥମ ବର୍ଷର ସୁଧ ଉପରେ ଅର୍ଜିତ ସୁଧ।
