In each of the following questions, a statement of Assertion (A) is given followed by a corresponding statement of Reason (R) just below it. Of the statements, mark the correct answer as
Assertion : −63/147 and -21/-49 are equivalent rational numbers.
Reason : If the numerator and denominator of a rational number are multiplied or divided by a same non-zero integer, we get a rational number which is said to be equivalent to the given rational number.

A If both assertion and reason are true and reason is the correct explanation of assertion.
B If both assertion and reason are true but reason is not the correct explanation of assertion.
C If assertion is true but reason is false.
D If assertion is false but reason is true.

Directions : In each of the following questions, a statement of Assertion (A) is given followed by a corresponding statement of Reason (R) just below it. Of the statements, mark the correct answer as
Assertion : The sum of 278 + 691 + 221 is 1901.
Reason : If a, b and c are three whole numbers, then (a + b) + c = a + (b + c).

A If both assertion and reason are true and reason is the correct explanation of assertion.
B If both assertion and reason are true but reason is not the correct explanation of assertion.
C If assertion is true but reason is false.

In each of the following questions, a statement of Assertion (A) is given followed by a corresponding statement of Reason (R) just below it. Of the statements, mark the correct answer as
Assertion : The median of the data 105, 103, 102, 107, 120, 124, 111 is 124.
Reason : When the number of observations(n) is odd, then the median is the value of the (n/2+1)th observation. If the number of observations(n) is even, then the median is the mean of the (n/2)th observation and the (n/2+1)th observation.

A If both assertion and reason are true and reason is the correct explanation of assertion.
B If both assertion and reason are true but reason is not the correct explanation of assertion.
C If assertion is true but reason is false.
D If assertion is false but reason is true.
