Column ? I | Column - II |
A. 12 is a | (p) prime number |
B. 2, 7 are | (q) not a rational number |
C. 2 is a | (r) composite number |
D. \[\sqrt{2}\] | (s) coprime numbers |
A) \[\text{A}-\left( \text{s} \right),\text{B}-\left( \text{r} \right),\text{C}-\left( \text{q} \right),\text{D}-\left( \text{p} \right)\]
B) \[~\text{A}-\left( \text{r} \right),\text{B}-\left( \text{p} \right),\text{C}-\left( \text{s} \right),\text{D}-\left( \text{q} \right)\]
C) \[\text{A}-\left( \text{q} \right),\text{B}-\left( \text{r} \right),\text{C}-\left( \text{s} \right),\text{D}-\left( \text{p} \right)\]
D) \[\text{A}-\left( \text{r} \right),\text{B}-\left( \text{s} \right),\text{C}-\left( \text{p} \right),\text{D}-\left( \text{q} \right)\]
Correct Answer: D
Solution :
(A) ? (r) [\[a\times \frac{1}{a}=1=\frac{1}{a}\times a\] \[\frac{1}{a}\]\[a\times (b+c)=a\times b+a\times c\] it is a composite number] (B ? (s) [\[(b+c)\times a=b\times a+c\times a\] g.c.d. between 2 and 7 = 1] (C) ? (p) [\[3=\frac{3}{1}\] 2 is a prime number] (D) ? (q) [\[0=\frac{0}{1}\]\[\frac{a+b}{2}\] is not a rational number]You need to login to perform this action.
