Aତିନି-ଚତୁର୍ଥାଂଶ
Bଏକ-ଚତୁର୍ଥାଂଶ
Cଏକ-ଦ୍ୱିତୀୟାଂଶ
Dଚାରି-ପଞ୍ଚମାଂଶ
Answer & Solution
Correct answer: A. ତିନି-ଚତୁର୍ଥାଂଶ
1. A ପ୍ରତିଦିନ କାର୍ଯ୍ୟର ଏକ-ବିଂଶତିତମାଂଶ ସମ୍ପୂର୍ଣ୍ଣ କରେ।
2. 5 ଦିନରେ ସେ 5 x 1/20 = 5/20 ସମ୍ପୂର୍ଣ୍ଣ କରେ।
3. ତାହା ସରଳ ହୋଇ କାର୍ଯ୍ୟର ଏକ-ଚତୁର୍ଥାଂଶ ସମ୍ପାଦିତ ହୋଇଥିବା ଦର୍ଶାଏ।
4. ଅବଶିଷ୍ଟ କାର୍ଯ୍ୟ ହେଉଛି 1 - 1/4।
5. ତେଣୁ କାର୍ଯ୍ୟର ତିନି-ଚତୁର୍ଥାଂଶ ଏବେ ମଧ୍ୟ ବାକି ଅଛି। ଏକ-ଚତୁର୍ଥାଂଶ ଉତ୍ତର ଦେବା ଶେଷ ହୋଇଥିବା ଅଂଶକୁ ସୂଚାଏ, ବାକି ଥିବା ଅଂଶକୁ ନୁହେଁ।
