The following Assertion and Reason questions are based on Chapter 2: Arithmetic Expressions from the NCERT Class 7 Mathematics textbook. Each question has four options - read both the Assertion (A) and Reason (R) carefully before selecting your answer.
How to attempt Assertion & Reason questions:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is NOT the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, but R is true.
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is NOT the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, but R is true.
Assertion & Reason Questions
1
Assertion (A): An arithmetic expression combines numbers and operation signs.
Reason (R): Evaluating it according to operation rules produces a numerical value.
Reason (R): Evaluating it according to operation rules produces a numerical value.
Answer: (a)
Both A and R are true, and R is the correct explanation of A. An expression represents a calculation.
2
Assertion (A): The expressions 10 + 2 and 3 x 4 have the same value.
Reason (R): The expression 24 divided by 2 also has value 12.
Reason (R): The expression 24 divided by 2 also has value 12.
Answer: (b)
Both A and R are true, but R is NOT the correct explanation of A. All are true, but the third expression does not explain equality of the first two.
3
Assertion (A): The value of 8 + 3 x 2 is 14.
Reason (R): Addition must always be performed before multiplication.
Reason (R): Addition must always be performed before multiplication.
Answer: (c)
A is true, but R is false. Multiplication first gives 8 + 6 = 14.
4
Assertion (A): The expressions 7 + 5 and 7 x 5 are equal.
Reason (R): Their values are 12 and 35 respectively.
Reason (R): Their values are 12 and 35 respectively.
Answer: (d)
A is false, but R is true. The values are unequal.
5
Assertion (A): Brackets can change the value of an expression.
Reason (R): In (8 + 3) x 2, the bracketed addition is performed first.
Reason (R): In (8 + 3) x 2, the bracketed addition is performed first.
Answer: (a)
Both A and R are true, and R is the correct explanation of A. The brackets prescribe a different grouping.
6
Assertion (A): The value of 20 - 4 x 3 is 8.
Reason (R): The value of (20 - 4) x 3 is 48.
Reason (R): The value of (20 - 4) x 3 is 48.
Answer: (b)
Both A and R are true, but R is NOT the correct explanation of A. Both are true, but the second does not explain the first.
7
Assertion (A): The value of 18 divided by (3 + 3) is 6.
Reason (R): The bracket has value 3.
Reason (R): The bracket has value 3.
Answer: (c)
A is true, but R is false. The bracket is 6, so the expression equals 3.
8
Assertion (A): Removing brackets never changes an expression.
Reason (R): Brackets specify which operation is grouped first.
Reason (R): Brackets specify which operation is grouped first.
Answer: (d)
A is false, but R is true. Ignoring grouping can change the value.
9
Assertion (A): Terms in a sum are separated by plus or minus signs at the outer level.
Reason (R): Recognising terms helps an expression be read and rearranged correctly.
Reason (R): Recognising terms helps an expression be read and rearranged correctly.
Answer: (a)
Both A and R are true, and R is the correct explanation of A. The outer addition structure determines the terms.
10
Assertion (A): The expression 5 x 6 + 2 has two terms.
Reason (R): The product 5 x 6 is evaluated as 30.
Reason (R): The product 5 x 6 is evaluated as 30.
Answer: (b)
Both A and R are true, but R is NOT the correct explanation of A. Both are true, but its numerical product does not explain the general term definition.
11
Assertion (A): The value of 40 divided by 5 x 2 is 4.
Reason (R): Division and multiplication of equal priority are handled left to right.
Reason (R): Division and multiplication of equal priority are handled left to right.
Answer: (c)
A is true, but R is false. The value is 8 x 2 = 16.
12
Assertion (A): The symbol = means one side is approximately the other.
Reason (R): Equality means both expressions have exactly the same value.
Reason (R): Equality means both expressions have exactly the same value.
Answer: (d)
A is false, but R is true. Approximation uses a different idea.
13
Assertion (A): Two different expressions can have the same value.
Reason (R): For example, 15 - 3 and 24 divided by 2 both equal 12.
Reason (R): For example, 15 - 3 and 24 divided by 2 both equal 12.
Answer: (a)
Both A and R are true, and R is the correct explanation of A. The example directly demonstrates the assertion.
14
Assertion (A): The sign < compares the values of two expressions.
Reason (R): An expression can contain more than one operation.
Reason (R): An expression can contain more than one operation.
Answer: (b)
Both A and R are true, but R is NOT the correct explanation of A. Both are true, but multiple operations do not explain the less-than sign.
15
Assertion (A): The expression 6 + 18 divided by 3 has value 8.
Reason (R): It is evaluated as (6 + 18) divided by 3.
Reason (R): It is evaluated as (6 + 18) divided by 3.
Answer: (c)
A is true, but R is false. Without brackets, division first gives 12.
16
Assertion (A): The value of 5 x (2 + 4) is 14.
Reason (R): The bracketed sum is 6, so the product is 30.
Reason (R): The bracketed sum is 6, so the product is 30.
Answer: (d)
A is false, but R is true. The reason gives the correct value.
17
Assertion (A): A complex expression should be evaluated using its grouping and operation priority.
Reason (R): These conventions give different readers the same value.
Reason (R): These conventions give different readers the same value.
Answer: (a)
Both A and R are true, and R is the correct explanation of A. Shared rules remove ambiguity.
18
Assertion (A): The expression 100 - 25 - 10 is evaluated left to right as 65.
Reason (R): Subtraction is not commutative.
Reason (R): Subtraction is not commutative.
Answer: (b)
Both A and R are true, but R is NOT the correct explanation of A. Both are true, but noncommutativity is a general property rather than the complete calculation.
19
Assertion (A): Interchanging 9 - 4 to 4 - 9 changes the value.
Reason (R): Subtraction is commutative.
Reason (R): Subtraction is commutative.
Answer: (c)
A is true, but R is false. The values differ because subtraction is not commutative.
20
Assertion (A): Every arithmetic expression must contain an equality sign.
Reason (R): An expression such as 3 + 5 has a value without being an equation.
Reason (R): An expression such as 3 + 5 has a value without being an equation.
Answer: (d)
A is false, but R is true. An equality relates expressions; it is not required inside one.
