ASSERTION- REASON / VERY SHORT
DIRECTION: In the question number 7 and 8, a statement of Assertion
(A) is followed by a statement of Reason (R).
Choose the correct option
Statement A(Assertion): If the pair of lines are coincident. Then we say
that pair is consistent and it has a unique solution.
Statement R(Reason): If the pair of lines are parallel. Then than the pair
has no solution and is called inconsistent pair of equations.
(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 and 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.
Q7 Assertion (A): Rational number lies between is
Reason (R):Rational number lying between two rational numbers a
and b is
Q8 Assertion (A): is an irrational number.
Reason (R):A number is called irrational, if it cannot be written in
, the form p/q, where p and q are integers and q≠0
CASE BASED/SOURCE BASED
Q9 Shivam has made a project on real numbers, where he finely
explained the basic operations of irrational number on real numbers.
He also included some assessment questions at the end of his
project as listed below. Answer them.
(i) Simplify :
(ii) Find two irrational number between and
(iii) Find two rational number between and
Q 10 Case Study
Two friends were given a project to tag the numbers given to them
as R , IR which are short form for rational number , irrational
number respectively . The numbers are : 1.707007000….., 1/5 , ,
