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.

Real Numbers (NCERT Exemplar Solutions Ex 1.1)

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

PROBLEM OF POVERTY IN INDIA
(Q and A)

Class 11 - Economics

Q1: Why is calorie-based norm not adequate to identify the poor?

Answer: The calorie-based norm is not adequate to identify the poor because of the following reasons:
ⅰ This mechanism does not differentiate a very poor from other poor. It categorises them into one category that is, ‘poor’. Consequently, it indicates whole class of poor and not, especially, those poor who are the most needy.

ⅱ This mechanism uses inappropriate proxies for income like Monthly Per Capita Expenditure (MPCE), etc. These items do not act as suitable and appropriate proxies for income to measure calorie requirements.

ⅲ This mechanism does not consider various important factors that are associated with poverty. These factors are health care, clean drinking water, proper sanitation and basic education. Mere estimation of calorie intake does not reflect the true economic condition of an individual.

ⅳ Another shortcoming of calorie-based norm is that it fails to account for social factors that freedom, etc. exaggerate and worsen poverty like ill health, lack of access to resources, lack of civil and political

Therefore, because of these shortcomings in the calorie-based norm, it cannot be used to identify the poor.
