Option 3: Jaw : Jazzy
Option 4: Resin : Resist
Correct Answer: Cackle : Giggle
Solution : Given: Cancel : Drop (Cancel means to decide not to conduct or perform and drop is the synonym of Cancel.)
Let's check the options – First option: Cackle : Giggle; Cackle means laughing in a loud, harsh way. Giggle means laughing lightly and
Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the following set. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits.) (7, 150, 23) (11, 75, 4)
Option 1: (4, 108, 16)
Option 2: (8, 90, 11)
Option 3: (9, 80, 11)
Option 4: (15, 140, 13)
Correct Answer: (15, 140, 13)
Solution : Given: (7, 150, 23); (11, 75, 4)
Here, (7, 150, 23)→(7 + 23) × 5 = 30 × 5 = 150 (11, 75, 4)→(11 + 4) × 5 = 15 × 5 = 75
Now, let's check the options
Question : The cliff of a mountain is 180 m high and the angles of depression of two ships on either side of the cliff are 30° and 60°. What is the distance between the two ships?
Option 1: $400$ metres
Option 2: $400\sqrt{3}$ metres
Option 3: $415.68$ metres
Option 4: $398.6$ metres
Correct Answer: $415.68$ metres
Solution : AD = Cliff = 180 metres $\angle$ABD = 60°, $\angle$ACD = 30° From ∆ABD, $\tan 60° = \frac{AD}{BD}$ ⇒$\sqrt{3}=\frac{180}{BD}$ $\therefore BD=60\sqrt{3}$ metres From ∆ACD, $\tan 30° = \frac{AD}{CD}$ ⇒ $\frac{1}{\sqrt{3}}=\frac{180}{CD}$ $\therefore CD=180\sqrt{3}$ metres ∴ BC = BD + DC $\therefore BC=60\sqrt{3}+180\sqrt{3} =240\sqrt{3}=(240 × 1.732)=
Question : Direction: In this question, a word is represented by only one set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabets as in the two matrices, given below. The columns and rows of Matrix (I) are numbered from 0 to 4 and that of Matrix (II) are numbered from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, e.g. A can be represented by 03,55, etc. and P can be represented by 10,44, etc. Similarly, you have to identify the set for the word TOWN.
Option 1: 40, 86, 03, 59
Option 2: 68, 75, 30, 43
Option 3: 68, 76, 58, 21
Option 4: 40, 33, 58, 22
Correct Answer: 40, 33, 58, 22
Solution : Given – TOWN
Option first: 40, 86, 03, 59
TOAN
Option second: 68, 75, 30, 43
TOWI
Option third: 68, 76, 58, 21
TIWU
Option fourth: 40, 33, 58, 22
TOWN
The fourth set represents the word TOWN.

Question : $\theta$ is a positive acute angle and $\sin\theta-\cos\theta=0$, then the value of $\sec\theta+\operatorname{cosec}\theta$ is:
Option 1: $2$
Option 2: $\sqrt{3}$
Option 3: $2\sqrt{2}$
Option 4: $3\sqrt{2}$
Correct Answer: $2\sqrt{2}$
Solution : Given: $\sin\theta-\cos\theta=0$ ⇒ $\sin\theta=\cos\theta$ ⇒ $\sin\theta=\sin\;(90°-\theta)$ ⇒ $2\theta=90°$ ⇒ $\theta=45°$ So, $\sec\theta+\operatorname{cosec}\theta$ $= \sec 45°+ \operatorname{cosec} 45°$ $= \sqrt{2}+\sqrt{2}$ $= 2\sqrt{2}$ Hence, the correct answer is $2\sqrt{2}$.
Question : The railway fares for air-conditioned sleepers and ordinary sleeper classes are in the ratio of 4 : 1. The number of passengers travelling by air-conditioned sleeper and ordinary sleeper classes was in the ratio of 3 : 25. If the total collection was Rs. 37000. How much did air-conditioned sleeper passengers pay?
Option 1: Rs. 15000
Option 2: Rs. 10000
Option 3: Rs. 12000
Option 4: Rs. 16000
Correct Answer: Rs. 12000
Solution : The ratio of fares for air-conditioned classes to ordinary classes = 4 : 1 The ratio of the number of passengers in air-conditioned classes to ordinary classes = 3 : 25 Corresponding compounding ratio = (4 × 3) : (1 × 25) = 12
