Question 1

In 2017 the sales of each brand increased by the same percentage as it did in the year 2016. What will be the approximate average sales (in units) of mobiles per brand in year 2017?

Accepted Answer

Calculate the percentage increase for each brand from 2015 to 2016. Apply this same percentage to the 2016 sales to find 2017 sales. Finally, find the average of these 2017 values.

Question 2

If [4(2x/5 - 3/2)]/3 + 7/5 = 37/5, then what is the value of x?

Accepted Answer

Subtract 7/5 from 37/5 to get 6. Multiply by 3 and divide by 4 to get 2x/5 - 3/2 = 9/2. Adding 3/2 gives 2x/5 = 6, so x = 15.

Question 3

Area of 4 walls of a cuboid is 57 sq m, if its length is 5.5 m and height is 3 m. What is its breadth (in m)?

Accepted Answer

The area of 4 walls is 2h(l + b). Substituting the values: 2 × 3 × (5.5 + b) = 57. This gives 6(5.5 + b) = 57, so 5.5 + b = 9.5, meaning b = 4 m.

Question 4

From the given words, select the word which cannot be formed using the letters of the given word. HUMBLING HUMBLING

Accepted Answer

The word 'HUMBLING' does not contain the letter 'E'. Therefore, the word 'BLUE' cannot be formed using its letters.

Question 5

A trader had 960 kgs of rice. He sold a part of it at 20% profit and the rest at 8% profit, so that he made a total profit of 12%. How much rice (in kgs) did he sell at 8% profit?

Accepted Answer

Using alligation, the ratio of quantities sold at 20% and 8% profit is (12-8):(20-12) = 4:8 = 1:2. The quantity sold at 8% is (2/3) of 960 kg, which equals 640 kg.

Question 6

Which of the following river originates in Nepal and flows into the Ganges?

Accepted Answer

The Kosi river originates in the Himalayas in Nepal and flows south into India, where it joins the Ganges in Bihar. The other rivers belong to the Indus river system.

Question 7

In a certain code language, "RAIN" is written as "OHBQ". How is "SUMMER" written in that code language?

Accepted Answer

Reverse the word, then apply +1, -1, +1, -1 alternately to the letters. SUMMER reversed is REMMUS. Applying the pattern gives SDNLVR.

Question 8

2 men or 3 women can complete a job in 96 days. Then 6 men and 7 women will complete the same job in how many days?

Accepted Answer

Equate efficiencies: 2M = 3W, so M:W = 3:2. Total work = 2 × 3 × 96 = 576 units. Efficiency of 6M + 7W = 18 + 14 = 32. Days = 576/32 = 18.

Question 9

What is the name of a group of similar cells performing a specific function? ?

Accepted Answer

A group of similar cells that work together to perform a specific function is called a tissue. Multiple tissues then combine to form an organ.

Question 10

D and E are points on side AB and AC of ΔABC. DE is parallel to BC. If AD:DB = 2:5 and area of ΔADE is 8 cm sq, what is the area (in sq cm) of quadrilateral BDEC?

Accepted Answer

Since DE || BC, ΔADE ~ ΔABC. The ratio of sides AD:AB is 2:7, so the area ratio is 4:49. Area of ΔABC = (49/4)*8 = 98. Area of BDEC = 98 - 8 = 90.

Question 11

A writ of _________ means that the court orders that the arrested person should be presented before it.

Accepted Answer

Habeas Corpus literally means 'to have the body of'. It is a writ issued by a court directing the detaining authority to produce the arrested person before it to examine the legality of detention.

If ENCRYPT is coded as VMXIBKG, then how will ARC be coded as?

Accepted Answer

Each letter is replaced by its opposite letter in the English alphabet (sum of positions = 27). Thus, A becomes Z, R becomes I, and C becomes X, giving ZIX.

Question 13

In the following question, select the related number group from the given alternatives. 19 : 367 : : ? : ? 19 : 367 : : ? : ?

Accepted Answer

The pattern is x : x² + 6. Here, 19² + 6 = 361 + 6 = 367. Similarly, 21² + 6 = 441 + 6 = 447.

Question 14

Who was the 2016 Men's Kabaddi World Cup Runner-Up?

Accepted Answer

India won the 2016 Men's Kabaddi World Cup by defeating Iran in the final match. Therefore, Iran was the runner-up of the tournament.

Question 15

What is the simplified value of (sec A + cos A)(sec A – cos A)? ?

Accepted Answer

Use (a+b)(a-b) = a² - b² to get sec² A - cos² A. Substitute sec² A = 1 + tan² A and cos² A = 1 - sin² A to get tan² A + sin² A.

Question 16

________ was imprisoned for the rest of his life by Aurangzeb.

Accepted Answer

Aurangzeb imprisoned his father, Shah Jahan, in the Agra Fort in 1658 after a bitter war of succession. Shah Jahan spent his last eight years there until his death.
