Real Numbers 

(NCERT Exemplar Solutions Ex 1.1)

Question 4:
If the HCF of 65 and 117 is expressible in the form 65m − 117, then the value of m is
(A) 4
(B) 2
(C) 1
(D) 3

Answer: (B) 2

Explanation:
Using Euclid’s division algorithm,
b = aq + r, 0 ≤ r < a [∵ dividend = divisor × quotient + remainder]
⇒ 117 = 65 × 1 + 52
⇒ 65 = 52 × 1 + 13
⇒ 52 = 13 × 4 + 0
∴ HCF (65, 117) = 13 .... (i)

Also, given that, HCF (65, 117) = 65m – 117 ... (ii)

From Equations (i) and (ii), we get
65m − 117 = 13
⇒ 65m = 130
⇒ m = 2

Class 9 English - The Road Not Taken ( Questions and Answers)(#cbsenotes)(#eduvictors)

The Road Not Taken

Q & A

The poem is a metaphor about the dilemma of making decisions that we have to make in our lives.

Poet: Robert Frost (March 26, 1874 – January 29, 1963)

Q1: Where does the traveller find himself? What problem does he face?

Answer: The traveller finds himself standing and waiting before the two diverged roads in the yellow wood. Robert Frost feels confused and faces the problem in deciding the appropriate road to be travelled on. Both the roads seem fair to him but it is difficult for him to determine which road can lead to his favour. Metaphorically, the poet is in the dilemma state of choosing the right choice for his future endeavours.

Question 1:
For some integer m, every even integer is of the form

(A) m
(B) m + 1
(C) 2m
(D) 2m + 1


Answer: (C) 2m

Explanation:
Even integers are -4, -2, 0, 2, 4, 6 ...
Let m = integers[Since, here integer is represented by m]
such that m = ⋯ , −1, 0, 1, 2, 3, ...
∴ 2m = ⋯ , −2, 0, 2, 4, 6, ...
∴ even integers can be represented in the form of 2m
