MCQ
Assertion (A): $7.3 \times 0.3=2.19$.
Reason ( $R$ ): When we multiply a decimal by 10 , we shift the decimal point to the right by one place.
  • A
    Both Assertion (A) and Reason $(R)$ are true and Reason $(R)$ is the correct explanation OF Assertion (A).
  • ✓
    Both Assertion $(A)$ and Reason $(R)$ are true and Reason $(R)$ is not the correct explanation of Assertion (A).
  • C
    Assertion (A) is true but Reason (R) is false.
  • D
    Assertion (A) is false but Reason (R) is true.
✓

Answer

Correct option: B.
Both Assertion $(A)$ and Reason $(R)$ are true and Reason $(R)$ is not the correct explanation of Assertion (A).
(b):
$\begin{array}{r}73 \\ \times 3 \\ \hline 219\end{array}$
$
\therefore 7.3 \times 0.3=2.19
$
So, A is true. R is clearly true, but R is not the correct explanation of A .

Directions: In the following questions, the Assertions $(A)$ and Reason$(s)$ $(R)$ have been put forward. Read both the statements carefully and choose the correct alternative from the following:
Assertion: An equation whose solution is not whole number is $4x = 1$.
Reason: Let the equation be $4x = 1$. On dividing both sides by $4$ then the value of $x$ is $\frac{1}{4}.\text{x}=\frac{1}{4}$ is the solution of above equation. $\frac{1}{4}$ is not a whole number.
