Assertion (A) : Half of a number is obtained by dividing it by 2. Reason (R) : The fractions $\frac{x}{y}$ and $\frac{y}{x}$ are multiplicative inverse of each other.
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 but 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 but Reason (R) is not the correct explanation of Assertion (A).
$\frac{4}{5}$ of a number is 64 . Half of that number is [Hint: Let $\frac{4}{5}$ of $x=64 \Rightarrow \frac{4}{5} \times x=64 \Rightarrow x=\left(64 \times \frac{5}{4}\right)=80$ Number $=80$. Find its half. $]$
Assertion (A) : The sum of two fractions is always a fraction. Reason (R) : For two fractions $\frac{a}{b}$ and $\frac{c}{d}$, we have $\frac{a}{b}+\frac{c}{d}=\frac{a d+b c}{b d}$
A
Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
B
Both Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A).
