alleryଯଦି 12 ଜଣ ଶ୍ରମିକ ଏକ କାର୍ଯ୍ୟକୁ 8 ଦିନରେ ସମ୍ପୂର୍ଣ୍ଣ କରିପାରନ୍ତି, ତେବେ 16 ଜଣ ଶ୍ରମିକ ଏହାକୁ ସମ୍ପୂର୍ଣ୍ଣ କରିବେ:
A4 ଦିନ
B6 ଦିନ
C9 ଦିନ
D10 ଦିନ
Answer & Solution
Correct answer: B. 6 ଦିନ
1. ମୋଟ କାର୍ଯ୍ୟ ହେଉଛି 12 x 8 = 96 worker-days।
2. ଦଳର ଆକାର ବଦଳିଲେ ମଧ୍ୟ ଏହି ମୋଟ ପରିମାଣ ବଦଳେ ନାହିଁ।
3. 16 ଜଣ ଶ୍ରମିକଙ୍କ ସହିତ ଆବଶ୍ୟକ ସମୟ ହେଉଛି 96 / 16।
4. ତାହା ହେଉଛି 6 ଦିନ।
5. ଅଧିକ ଶ୍ରମିକ ଅର୍ଥ କମ୍ ଦିନ, ତେଣୁ ଉତ୍ତର ନିଶ୍ଚିତ ଭାବରେ 8 ରୁ କମ୍ ହେବ, ଯାହା 9 ଏବଂ 10 କୁ ବାଦ୍ ଦିଏ।
