Therefore, the correct answer is for.
Question : Directions: Three of the following four triads are alike in a certain way as they are formed by performing the same mathematical operations among themselves and thus form a group. Which triad does not belong to that group?
Option 1: 11 : 21 : 121
Option 2: 2 : 3 : 4
Option 3: 7 : 15 : 49
Option 4: 9 : 17 : 81
Correct Answer: 7 : 15 : 49
Solution : Let's check the given options – First option: (11 : 21 : 121)→11 + (11 – 1) = 11 + 10 = 21; 112 = 121 Second option: (2 : 3 : 4)→2 + (2 – 1) = 2 + 1 = 3; 22 = 4 Third option: (7 : 15 : 49)→7 + (7 – 1) = 7 + 6 = 13 ≠ 15; 72 = 49 Fourth option: (9 : 17 : 81)→9 + (9 – 1) = 9 + 8 = 17; 92 = 81
Therefore, only the third option does not follow the pattern of the others. Hence, the third option is correct.
Question : Direction: X goes 15 metres North, then turns right and walks 20 metres. then again turns right and walks 10 metres, then again turns right and walks 20 metres. How many metres has he travelled from his original position?
Option 1: 5 m
Option 2: 10 m
Option 3: 15 m
Option 4: 20 m
Correct Answer: 5 m
Solution : As per the given information, the movement of X will look as follows –
According to the above figure, the distance that X has traveled from his original position = AE = 5 m.
Hence, the first option is correct.
Question : Three bottles of equal capacity contain mixtures of milk and water in ratios 2 : 5, 3 : 4, and 4 : 5. These three bottles are emptied into a large bottle. What will be the ratio of milk and water respectively in the large bottle?
Option 1: 73 : 106
Option 2: 73 : 116
Option 3: 73 : 113
Option 4: 73 : 189
Correct Answer: 73 : 116
Solution : Let the capacity of each bottle be $x$ units. Bottle 1 has milk : water = 2 : 5 Bottle 2 has milk : water = 3 : 4 Bottle 3 has milk : water = 4 : 5 Bottle 1 contains milk = $\frac{2x}{7}$, water = $\frac{5x}{7}$ Bottle 2 contains milk = $\frac{3x}{7}$, water = $\frac{4x}{7}$ Bottle 3 contains milk = $\frac{4x}{9}$, water = $\frac{5x}{9}$ When mixed, the ratio of milk and water is: $= (\frac{2x}{7}+\frac{3x}{7}+\frac{4x}{9}) : (\frac{5x}{7}+\frac{4x}{7}+\frac{5x}{9})$ $= (\frac{18x+27x+28x}{63}) : (\frac{45x+36x+35x}{63})$ $= 73: 116$ Hence, the correct answer is 73 : 116.

Question : Comprehension: In the following passage, some words have been deleted. Read the passage carefully and select the most appropriate option to fill in each blank.

I realised very quickly that although in (1)_______ ways it appears unchanged, in reality hardly anything is the same. All the pretty cottages are there, of course, and both the traditional farmhouses. (2)_______, none of the inhabitants are country people. All of them are commuters, who leave early every morning for the nearby town. Neither of the farmhouses is attached to a farm these days; the land (3)_______ and is managed by somebody in an office somewhere who has little interest in the village (4)_______. There are a few new houses but, they have no local character. You can see the same style anywhere in the country. The whole village, (5)_______, has been tidied up so much that it looks no more picturesque than any suburban street.
Question: Select the most appropriate option to fill in the blank number 3.
Option 1: had been sold
Option 2: sells
Option 3: sold
Option 4: has been sold
Correct Answer: has been sold
Solution : The correct choice is the third option.
Explanation: The phrase "the land has been sold" is in the present perfect tense. In the context of the passage, this tense is suitable because it conveys a connection between a past action (the sale of the land) and the present state (the land being managed by somebody in an office). The present perfect tense indicates relevance to the current situation.
So, the complete sentence would be: "Neither of the farmhouses is attached to a farm these days; the land has been sold and is managed by somebody in an office somewhere who has little interest in the village."

Question : E, F, G, and H are four points lying on the circumference of a circle to make a cyclic quadrilateral. If $\angle {FGH}=57^{\circ}$, then what will be the measure of the $\angle {HEF}$?
Option 1: $33^{\circ}$
Option 2: $123^{\circ}$
Option 3: $93^{\circ}$
Option 4: $143^{\circ}$
Correct Answer: $123^{\circ}$
Solution : E, F, G, and H form a cyclic quadrilateral. $\angle {FGH}=57^{\circ}$ In a cyclic quadrilateral, the sum of opposite angles is 180$^\circ$. So, $\angle {FGH} + \angle {HEF} = 180^\circ$ ⇒ $57^{\circ} + \angle {HEF} = 180^\circ$ ⇒ $\angle {HEF} = 180^\circ- 57^{\circ} = 123^\circ$ Hence, the correct answer is $123^\circ$.
Question : The value of 74 + 88 ÷ 8 × 10 of 5 – 90 ÷ 15 + {44 – (108 ÷ 12)} is:
Option 1: 700
Option 2: 653
Option 3: 770
Option 4: 605
Correct Answer: 653
Solution : Given expression, $74 + 88 ÷ 8 × 10\ \text{of}\ 5 - 90 ÷ 15 + {44 - (108 ÷ 12)}$ $= 74 + \frac{88}{8}\times50 - \frac{90}{15} + {44 - \frac{108}{12}}$ $= 74 + 11 \times 50- 6 + {44 - 9}$ $= 74 + 550 - 6 + 35$ $= 653$ Hence, the correct answer is 653.
