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.

Assertion : The place value and face value of digit 8 in 18,002,403 is 8 × 1,000,000 and 8 respectively.
Reason : Place value is value of digit itself and face value depends upon the place it occupies.
AIf 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.
