In Microsoft Word, _______ allows us to move selected paragraphs to the right.

Accepted Answer

In MS Word, the 'Increase Indent' feature pushes the selected paragraph away from the left margin towards the right. 'Decrease Indent' moves it back to the left.

Question 2

In the following question, correct the equation by interchanging the two signs. 6 ÷ 17 x 51 + 6 – 12 = – 4 6 ÷ 17 x 51 + 6 – 12 = – 4

Accepted Answer

Swap x and ÷: The equation becomes 6 x 17 ÷ 51 + 6 - 12. Using BODMAS, 17 ÷ 51 = 1/3. Then 6 x (1/3) = 2. Finally, 2 + 6 - 12 = 8 - 12 = -4.

Accepted Answer

Maharashtra has 19 Rajya Sabha seats and 48 Lok Sabha seats. It has the second-highest number of Rajya Sabha seats in India after Uttar Pradesh (31).

Question 6

In ΔPQR, ∠R = 54°, the perpendicular bisector of PQ at S meets QR at T. If ∠TPR = 46°, then what is the value (in degrees) of ∠PQR?

Accepted Answer

Since ST is the perpendicular bisector of PQ, TP = TQ, making ∠TQP = ∠TPQ = x. In ΔPQR, the sum of angles is (x + 46°) + x + 54° = 180°, giving x = 40°.

Question 7

Accepted Answer

The Food Security System in India consists of two main components: Buffer Stock and the Public Distribution System (PDS). Buffer stock ensures food availability during shortages.

Question 10

If on a Sale there is 30% discount on the marked price of Rs 2500, but the sale is done at Rs 1400 only. What additional discount (in %) did the customer get? 9/7/2017 Staff Selection Commision

Accepted Answer

The first discount reduces the price to 70% of 2500, which is Rs 1750. The final price is Rs 1400, giving an additional discount of Rs 350. Thus, (350/1750)*100 = 20%.

Question 11

____________ scheme by the Central Government states that an insurance of 10 lakhs will cover each passenger traveling by Indian Rail while booking a ticket if an amount of 92paise is paid.

Accepted Answer

The Railway Travel Insurance scheme allows passengers booking e-tickets via IRCTC to opt for a ₹10 lakh travel insurance cover by paying a nominal premium of 92 paise.

Question 12

The 3rd and 7th term of an arithmetic progression are -9 and 11 respectively. What is the 15th term?

Accepted Answer

Using the AP formula a + (n-1)d, we get a + 2d = -9 and a + 6d = 11. Solving gives d = 5 and a = -19. The 15th term is -19 + 14(5) = 51.

Question 13

The average age of Ram and Rahim is 18 years. The average age of Rahim and Ramesh is 25 years. The average age of Ram and Ramesh is 29 years. What is the age (in years) of the eldest of the three?

Accepted Answer

Sum of ages: Ram+Rahim=36, Rahim+Ramesh=50, Ram+Ramesh=58. Total sum of all three = (36+50+58)/2 = 72. The eldest is Ramesh: 72 - (Ram+Rahim) = 72 - 36 = 36 years.

Question 14

PQRS is a square, M is the mid-point of PQ and N is a point on QR such that NR is two-third of QR. If the area of ΔMQN is 48 cm2, then what is the length (in cm) of PR ?

Accepted Answer

Let the side of the square be a. MQ = a/2 and QN = a/3. Area of ΔMQN = 1/2 × a/2 × a/3 = a²/12 = 48. Thus, a = 24. Diagonal PR = a√2 = 24√2.

Question 15

Δ DEF is right angled at E. If m∠D = 45°, then what is the value of cosecF X cotD?

Accepted Answer

Since ∠E = 90° and ∠D = 45°, ∠F must be 45°. Thus, cosecF = cosec(45°) = √2 and cotD = cot(45°) = 1. Their product is √2 × 1 = √2.

Question 16

The winning candidate got how many more votes than the one who came second? 9/7/2017 Staff Selection Commision

Accepted Answer

Find the difference in votes or percentages between the first and second candidates from the given data chart, then calculate that difference from the total votes to get 6000.

Question 17

A spaceship travels at 1,260 km/h. How many metres does it travel in 1/10 th of a second?

Accepted Answer

Convert speed to m/s: 1260 × (5/18) = 350 m/s. Distance in 1/10 second = Speed × Time = 350 × (1/10) = 35 metres.

Question 18

If area of country B is 20,00,000 sq km, what is its population?

Accepted Answer

Based on the associated data chart (not provided here), apply the population density or ratio for country B to its area (20,00,000) to calculate the correct population of 10,00,000.

Question 19

While selling an article for Rs 18450, a person suffered a loss of 50%. At what price he should have sold the article (in Rs) to earn a profit of 50%?

Accepted Answer

A 50% loss means Rs 18450 is 50% of the cost price. Thus, CP = 18450 × 2 = 36900. For a 50% profit, the new selling price is 150% of CP, which is 36900 × 1.5 = 55350.

Question 20

If 40% of x = y, then y% of 40 is same as _____ of x.

Accepted Answer

Given y = 0.4x. We need y% of 40, which is 0.4y. Substituting y gives 0.4 * 0.4x = 0.16x, which is exactly 16% of x.
