Option 1: QEQUZA
Option 2: QEQUAZ
Option 3: QEQZUA
Option 4: QEQUAA
Correct Answer: QEQUZA
Solution : Given: WEIGHS is coded as QHEICW.
Reverse the letters of the word WEIGHS then subtract 2 from the place value of the letters alternately to obtain the required code – WEIGHS→SHGIEW Now, subtract 2 alternately from the place value of the letters of SHGIEW
Question : Directions: In the following question, a series is given with one term missing. Choose the correct alternative from the given ones that will complete the series. ar, cs, et, ?
Option 1: wy
Option 2: gv
Option 3: vb
Option 4: gu
Correct Answer: gu
Solution : Given: ar, cs, et, ?
Add 2 to the place value of the first letter and 1 to the place value of the second letter of the previous term to obtain the next term of the series – ar→a + 2 = c; r +
Question : The amount Rs. 2,100 became Rs. 2,352 in 2 years at Simple Interest. If the interest rate is decreased by 1%, what is the new interest?
Option 1: Rs. 210
Option 2: Rs. 220
Option 3: Rs. 242
Option 4: Rs. 252
Correct Answer: Rs. 210
Solution : Given: The amount Rs. 2,100 became Rs. 2,352 in 2 years at Simple Interest and the interest rate is decreased by 1%. 1% rate decrease for 1 year. So, the total decrease for 2 years is 2%. Now, 2% of 2100 is = $2100×\frac{2}{100}$

Question : If $A$ is an acute angle and $8\sec A=17$, find the value of $\tan A$.
Option 1: $\frac{15}{17}$
Option 2: $\frac{15}{8}$
Option 3: $\frac{8}{15}$
Option 4: $\frac{8}{17}$
Correct Answer: $\frac{15}{8}$
Solution : Given, $8\sec A=17$ ⇒ $\sec A=\frac{17}{8}$ We know, $\tan^2 A=\sec^2 A-1$ ⇒ $\tan^2 A=(\frac{17}{8})^2-1$ ⇒ $\tan^2 A=\frac{225}{64}$ ⇒ $\tan A=\frac{15}{8}$ Hence, the correct answer is $\frac{15}{8}$.
Question : Which of the following statements is/are not correct?
I. Force per unit volume is called pressure. II. Liquids can exert pressure on the walls of containers. III. Force acting on an object can cause a change in its state of motion but not its shape.
Option 1: Only I and II
Option 2: Only III
Option 3: I, II and III
Option 4: Only I and III
Correct Answer: Only I and III
Solution : The correct answer is Only I and III.
Pressure is defined as the force exerted on the surface of objects per unit area. The first statement given in the question is incorrect.
Liquids can exert pressure on the walls of the containers.
Question : Directions: Select the option in which the numbers share the same relationship in the set as that shared by the numbers in the given set. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g.13 – operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.) (432, 348, 264) (288, 337, 386)
Option 1: (412, 390, 328)
Option 2: (304, 368, 412)
Option 3: (348, 317, 286)
Option 4: (264, 199, 114)
Correct Answer: (348, 317, 286)
Solution : Given: (432, 348, 264); (288, 337, 386)
The pattern is as follows – (432, 348, 264)→(432 + 264) ÷ 2 = 696 ÷ 2 = 348 (288, 337, 386)→(288 + 386) ÷ 2 = 674 ÷ 2 = 337

Question : Directions: In the following question, a series is given, with one term missing. Choose the correct alternative from the given ones that will complete the series. T, R, P, N, ?
Option 1: V
Option 2: M
Option 3: L
Option 4: E
Correct Answer: L
Solution : Given: T, R, P, N, ?
Subtract two from the positional value of letters given in the series – T – 2 = R; R – 2 = P; P – 2 = N; N – 2 = L
So, the missing term is L.
Question : In an army selection process, the ratio of selected to unselected candidates was 4 : 1. If 60 fewer candidates had applied and 20 fewer were selected, the ratio of selected to unselected candidates would have been 5 : 1. How many candidates had applied for the process?
Option 1: 1250
Option 2: 3300
Option 3: 900
Option 4: 950
Correct Answer: 900
Solution : Let the selected and unselected candidates be $4x$ and $x$ respectively. Total number of candidates = $4x+x=5x$ If 90 fewer candidates had applied, the total number of candidates = $5x - 60$ If 20 fewer were selected, the number of selected candidates then = $4x
