Question
Statement A (Assertion): ๐ฅ = 3 and ๐ฆ = 2 is a solution of the linearequation ๐๐ + ๐๐ = ๐๐.Statement R( Reason) : ๐ฅ = 4 and ๐ฆ = 2 is a solution of the linearequation ๐ + ๐๐ = ๐๐.(a) Both assertion (A) and reason (R) are true and reason (R) is thecorrect explanation of assertion (A)(b) Both assertion (A) and reason (R) are true and reason (R) is not thecorrect explanation of assertion (A)(c) Assertion (A) is true but reason(R) is false.(d) Assertion (A) is false but reason(R) is true.
Solution
To solve this, we need to substitute the given values of x and y into the equations and see if they hold true.
For Statement A (Assertion): The given equation is 2x + 3y = 12. Substituting x = 3 and y = 2, we get 23 + 32 = 6 + 6 = 12. Since the left side equals the right side, Statement A is true.
For Statement R (Reason): The given equation is x + 3y = 10. Substituting x = 4 and y = 2, we get 4 + 3*2 = 4 + 6 = 10. Since the left side equals the right side, Statement R is also true.
However, Statement R is not the correct explanation of Statement A because the two statements are about different equations and different solutions.
So, the correct answer is (b) Both assertion (A) and reason (R) are true and reason (R) is not the correct explanation of assertion (A).
