Question
Statement-1 (Assertion): There are two rational numbers whose sum and product both are rationals.
Statement-2 (Reason): There are numbers which cannot be written in the form \( \frac{p}{q} \), \( q \neq 0 \), where \( p, q \) are integers.
Options:
(a) Statement-1 is true, Statement-2 is true; Statement-2 is a correct explanation for Statement-1.
(b) Statement-1 is true, Statement-2 is true; Statement-2 is not a correct explanation for Statement-1.
(c) Statement-1 is true, Statement-2 is false.
(d) Statement-1 is false, Statement-2 is true.
Solution
Take two rational numbers, for example:
\[ 2 \text{ and } 3 \]
Their sum:
\[ 2 + 3 = 5 \quad (\text{rational}) \]
Their product:
\[ 2 \times 3 = 6 \quad (\text{rational}) \]
So, Statement-1 is true.
Statement-2 is also true because irrational numbers exist (they cannot be written as \( \frac{p}{q} \)).
However, Statement-2 does not explain Statement-1.
- Statement-1 is true
- Statement-2 is true
- But Statement-2 is not the correct explanation
Final Answer
✔ Correct option: (b)
