Mumps (epidemic parotitis) is a viral disease of the human species, caused by the mumps virus. Before the development of vaccination and the introduction of a vaccine, it was a common childhood disease worldwide.

• Recently, to initiate the process of taking the country towards nutritional security, the Department of Food & Public Distribution (DFPD) has been running a “Centrally Sponsored Pilot Scheme on Fortification of Rice & its distribution through Public Distribution System”. Hence statement 1 is correct.
• The Pilot Scheme has been approved for a period of three years beginning 2019-2020 with a total budget outlay of Rs.174.6 Crore. Fifteen State Governments have identified their respective districts (1 district per state) for implementing the Pilot Scheme.
• Already 5 states of Andhra Pradesh, Gujarat, Maharashtra, Tamil Nadu and Chhattisgarh have started the distribution of fortified rice in their respective identified districts. Special focus would be placed on supplying fortified rice to the 112 specially identified Aspirational Districts of the country.
• The Food Safety and Standards Authority of India (FSSAI) has revealed plans to make fortification mandatory for edible oil and milk but has not made it mandatory yet. The Food Safety and Standards Authority (FSSAI) is mulling over making fortification in edible oil with Vitamin A and D mandatory, in a bid to combat the malnutrition challenges including micronutrient deficiencies in India. In 2018, the regulator had set standards for fortification for five category of staples which includes wheat flour and rice (with iron, vitamin B12 and folic acid), milk and edible oil (with Vitamins A and D) and double fortified salt (with iodine and iron). The fortification norms are currently voluntary. In addition, it is intensifying its focus on local staples such as rice, wheat and salt. Hence statement 2 is not correct.
• The Food Safety and Standards Authority of India (FSSAI) releases the STATE FOOD FORTIFICATION INDEX for different states and union territories of India. As per the recently released report Andhra Pradesh ranks first. Hence statement 3 is correct.

Bangladesh will start receiving electricity from a power plant in Jharkhand in March.

Dust particles in Jamshedpur and surrounding areas in Jharkhand have a high concentration of toxic metals.

Microsoft has started 'Project ELLORA' to promote local languages in India's digital world.

3 + 1² + 1 = 5
5 + 2² + 1 = 10
10 + 4² + 1 = 27

Reasoning:

• From the given statements, we know that both cars and fans are subsets of cats.
• However, there's no direct relationship established between cars and fans.
• We cannot conclude that all cars are fans (conclusion 1).
• Similarly, we cannot definitively say that some fans are cars (conclusion 2).

Therefore, neither conclusion follows logically from the given statements.

Answer: (D) Neither (1) nor (2) follows

A and B are children of D.
From (1), C is the brother B and son of E.
Since, the sex of D and E are not known. Hence (1) is not sufficient to answer the question.
From (2). F is the mother of B. Hence, F is also the mother of A. Hence D is the father of A.
Thus, (2) is sufficient to answer the question.

Taking A = 1, B = 2,………,T = 20,……….., Z = 26, we have :
AT = A × T = 1 × 20 = 20, BAT = B × A × T = 2 × 1 × 20 = 40.
So, CAT = C × A × T = 3 × 1 × 20 = 60.

In the given code, Z = 1, Y = 2, X = 3,…………..,C = 24, B = 25, Z = 26.
So, GO = 20 + 12 = 32 and SHE = 8 + 19 + 22 = 49.
Similarly, SOME = S + O + M + E = 8 + 12 + 14 + 22 = 56.

The difference would amount to 8% of the value borrowed. Thus 56 = 0.08 x sum borrowed in each case → Sum borrowed = Rs. 700.

Interest per year = Rs. 25. Thus, an interest of Rs. 50 would be earned in 2 years.

Total man days required = 600 man days. If 5 workers leave the job after ‘n’ days, the total work
would be done in 35 days. We have to find the value of ‘n’ to satisfy:
20 × n + (35 – n) × 15 = 600.
Solving for n, we get
20n – 15n + 35 × 15 = 600
5n = 75
n = 15.

Subhash can copy 200 pages in 40 hours (reaction to the first sentence). Hence, Prakash can copy
100 pages in 40 hours. Thus, he can copy 30 pages in 30% of the time: i.e. 12 hours.

Answer – c) 70% Explanation : take total women =100 Women less than or equal to 50 years = 80 and women above 50 years = 20 20 = women plays basketball 30% of the women above 50 plays basketball = 6 So remaining 14 women who plays basketball are less than or equal to 50 years So (14/20)*100 = 70%

Answer – b) 55.60 Explanation : tax = 40/100 = (10/100)*T, T = 4 so cost of tax free items = 60 – 4 – 0.40 = 55.60

Suppose total number of students in a certain dormitory = y
Then, total number of first-year students = y/2
Total number of first-year students who have not declared a major = (2/5)y
So, fraction of first-year students who have declared a major = (1/10)y
Total number of fraction of second-year students who have declared a major = (3/10)y
Total number of fraction of second-year students who have not declared a major = (1/5)y
Then, required fraction = (1/5)

Since he scored 96 marks in section A, he must have attempted 24 questions in that section and all should have been right.
So,
Number of questions attempted in section A = 24
Number of questions attempted in section B = 20
Number of questions attempted in section C = 16
And,
Number of correct attempted questions in section A = 24
Number of correct attempted questions in section B = 18
Number of correct attempted questions in section C = 12
Thus, in section C, he will get:
12 × 4 - 4 = 44 marks

15 C.P. = 20 S.P.

There is 25% loss.
