Answer & Solution
Correct answer: C. 5
1. 11 ଦ୍ୱାରା ବିଭାଜ୍ୟତା: (ଅଯୁଗ୍ମ ସ୍ଥାନରେ ଥିବା ଅଙ୍କଗୁଡ଼ିକର ଯୋଗଫଳ) - (ଯୁଗ୍ମ ସ୍ଥାନରେ ଥିବା ଅଙ୍କଗୁଡ଼ିକର ଯୋଗଫଳ) 11 ର ଏକ ଗୁଣିତକ ଅଟେ।
2. x3339 ପାଇଁ, ଡାହାଣ ପଟୁ: ଅଯୁଗ୍ମ ସ୍ଥାନଗୁଡ଼ିକ 9, 3, x; ଯୁଗ୍ମ ସ୍ଥାନଗୁଡ଼ିକ 3, 3। ଅଯୁଗ୍ମ ସ୍ଥାନର ଯୋଗଫଳ = 12 + x, ଯୁଗ୍ମ ସ୍ଥାନର ଯୋଗଫଳ = 6।
3. ପାର୍ଥକ୍ୟ = 6 + x। ବିଭାଜ୍ୟତା ପାଇଁ, 6 + x = 11, ତେଣୁ x = 5।
