Question : The LCM and ratio of the three numbers are 1386 and 3 : 7 : 11, respectively. The sum of the greatest and least numbers is:
Option 1: 60
Option 2: 64
Option 3: 84
Option 4: 108
Correct Answer: 84
Solution : The LCM and ratio of the three numbers = 1386 Let the numbers be $3x, 7x,$ and $11x$. According to the question: $(3\times7\times11)x=1386$ ⇒ $231x=1386$ $\therefore x=6$ Thus, Least number $= 3x=3\times6=18$ Greatest number $=11x=11\times6=66$ $\therefore$ Sum $=18+66=84$ Hence, the correct answer is 84.
Question : Which of the following is a cold-blooded animal?
Option 1: Ape
Option 2: Mouse
Option 3: Snake

Question : Directions: Q is to the east of S. E is to the south of S. P is to the northeast of Q and north of T. If T is to the south-east of Q, what is the position of S with respect to T? (All positions are arranged in GRID pattern)
Option 1: Southeast
Option 2: Southwest
Option 3: West
Option 4: Northwest
Correct Answer: Northwest
Solution : Firstly, we will draw the diagram as per the given instructions –
Now, we have to find the position of S with respect to T.
Therefore, S is in the northwest direction with respect to T. Hence, the fourth option is correct.
Question : Directions: Identify the option that is embedded in the following figure (rotation is NOT allowed).
Question : Directions: A tap can fill up a tank of 1250 litres in 4 hours, whereas another tap can fill the same tank in 8 hours. An outlet tap can empty that tank in 6 hours. If all three taps are opened simultaneously, then how much time will it take to fill the tank?
Option 1: 4.2 Hours
Option 2: 5 Hours
Option 3: 4.5 Hours
Option 4: 4.8 Hours
Correct Answer: 4.8 Hours
Solution : Time taken by tap A to fill the tank = 4 hours Tank filled by tap 1 in one hour = 1/4 part of the tank Time taken by tap B to fill the tank = 8 hours Tank filled by tap 2 in one hour = 1/8 part of the tank Time taken by tap C to empty the tank = 6 hours Tank emptied by tap 3 in one hour = 1/6 part of the tank So, the part of the tank filled in one hour when all three taps are opened simultaneously = 1/4 + 1/8 – 1/6 = (6 + 3 – 4)/ 24 = 5/24 Thus, time taken by 3 taps to fill the tank = 24/5 = 4.8 hours
So, the time taken by three taps to fill the tank is 4.8 hours. Hence, the fourth option is correct.
Question : Select the misspelt word.
Option 1: implore
Option 2: impeach

The use of "an" before "exhaustive" is necessary because "exhaustive" starts with a vowel sound. The article "an" is placed before the singular countable nouns starting with a vowel sound.
Therefore, the complete sentence should be: This is not an exhaustive list of words.
Question : Directions: Study the given pattern carefully and select the number that can replace the question mark (?) in it.
Option 1: 21
Option 2: 30
Option 3: 23
Option 4: 17
Correct Answer: 17
Solution : Given:
The pattern can be observed running horizontally along the rows. Row 1: (182 × 2) ÷ 26 = 364 ÷ 26 = 14 Row 2: (192 × 2) ÷ 16 = 384 ÷ 16 = 24 Row 3: (187 × 2) ÷ 22 = 374 ÷ 22 = 17
So, 17 is the missing number. Hence, the fourth option is correct.
