alleryn କ’ଣ ଏକ ଯୁଗ୍ମ ସଂଖ୍ୟା? I: n + 1 ଏକ ଅଯୁଗ୍ମ ସଂଖ୍ୟା ଅଟେ। II: n ହେଉଛି 3 ର ଏକ ଗୁଣିତକ।
Aକେବଳ II ପର୍ଯ୍ୟାପ୍ତ ଅଟେ
Bଏକତ୍ର ମଧ୍ୟ କୌଣସିଟି ପର୍ଯ୍ୟାପ୍ତ ନୁହେଁ
Cକେବଳ I ପର୍ଯ୍ୟାପ୍ତ ଅଟେ
Dଉଭୟ ଏକତ୍ର ଆବଶ୍ୟକ
Answer & Solution
Correct answer: C. କେବଳ I ପର୍ଯ୍ୟାପ୍ତ ଅଟେ
ଯଦି n + 1 ଅଯୁଗ୍ମ ହୁଏ, ତେବେ n ନିଶ୍ଚିତ ଭାବରେ ଯୁଗ୍ମ ହେବ, ଯେତେବେଳେ କି 3 ର ଗୁଣିତକଗୁଡ଼ିକ ଅଯୁଗ୍ମ କିମ୍ବା ଯୁଗ୍ମ ହୋଇପାରେ।
