Question : Directions: Select the correct mirror image of the given combination when the mirror is held at the right side of the image.
Option 1:
Option 2:
Option 3:
Option 4:
Correct Answer:
Solution : As per the mirror image properties, closer things appear closer to the mirror in the reflection. Here, according to the information provided, the mirror is placed on the right side of the figure (on line PQ). So, the left side of the reflected image will appear
Question : Directions: If 4 * 7 * 2 = 361 and 5 * 9 * 1 = 480, then 2 * 1 * 3 = ?
Option 1: 312
Option 2: 324
Option 3: 210
Option 4: 102
Correct Answer: 102
Solution : Given: 4 * 7 * 2 = 361 and 5 * 9 * 1 = 480
Like, 4 * 7 * 2 = 361→4 – 1 = 3; 7 – 1 = 6; 2 – 1 = 1→361 5 * 9 * 1 = 480;
Question : Directions: In the following question, select the related number from the given alternatives. 10 : 1000 :: 2 : ?
Option 1: 4
Option 2: 0.5
Option 3: 20
Option 4: 8
Correct Answer: 8
Solution : Given: 10 : 1000 :: 2 : ?
The second number is the cube of the first number in the given pair. 10 : 1000→(10)3 = 1000 Similarly, 2 : ?→(2)3 = 8
Hence, the fourth option is correct.
Question : Directions: Select the set in which the numbers are related in the same way as the numbers of 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.) (70, 14, 56) (88, 30, 58)
Option 1: (44, 24, 23)
Option 2: (59, 36, 25)
Option 3: (52, 19, 33)
Option 4: (38, 16, 24)
Correct Answer: (52, 19, 33)
Solution : Given: (70, 14, 56); (88, 30, 58)
Here, (70, 14, 56)→14 + 56 = 70 (88, 30, 58)→30 + 58 = 88
Now, let's check the given options – First option: (44, 24, 23)→24 + 23 = 47 ≠ 44 Second option: (59,
Question : Directions: Ram went 20 metres to the north, then turned towards the east and walked another 5 metres. Then, he turned towards the right and covered 20 metres. How far is he from the starting point?
Option 1: 3 m
Option 2: 4 m
Option 3: 5 m
Option 4: 6 m
Correct Answer: 5 m
Solution : Firstly, we will draw the diagram as per the given instructions –
In the above figure, O is the starting point and C is the finishing point. So, OC is the distance from the starting point. OC = AB = 5 metres
So, he
Question : If $(4a + \frac{5}{a} + 5)=14$, what is the value of $(16a^2+ \frac{25}{a^2})$?
Option 1: 25
Option 2: 36
Option 3: 41
Option 4: 40
Correct Answer: 41
Solution : $(4a + \frac{5}{a} + 5) = 14$ $⇒(4a + \frac{5}{a}) = 14-5 = 9$ $⇒(4a + \frac{5}{a})^2 = 9^2$ $⇒(16a^2+ \frac{25}{a^2} + 40) = 81$ $\therefore(16a^2+ \frac{25}{a^2})= 81-40 = 41$ Hence, the correct answer is 41.
Question : Direction: Arrange the following words as per their order in the dictionary.
(i) Ambitious
(ii) Ambiguous
(iii) Ambiguity
(iv) Animation
(v) Animals
Option 1: (iii), (ii), (i), (v), (iv)
Option 2: (iii), (ii), (iv), (v), (i)
Option 3: (iii), (ii), (iv), (i), (v)
Option 4: (iii), (ii), (v), (iv), (i)
Correct Answer: (iii), (ii), (i), (v), (iv)
Solution : Given:
Step 1: Compare the first letter of each word. Since, all the words start with the same letter A, after that move on to the next letter.
Step 2:
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 12,24, etc., and 'R' can be represented by 57, 76, etc. Similarly, you have to identify the set for the word.
'ROSE'
