EARSUQ → SQUARE → An equally four-sided geometrical shape.

IRTGNAEL→ TRIANGLE → A three-sided geometrical shape.

NAEGRCELT → RECTANGLE → A four-sided geometrical shape with two sides having equal length and other two sides having equal breadth.

RGETESNH → GREENTHS → The green growth or verdure. The greenery of anything.

Clearly, RGETESNH is not related to mathematics and is the odd one out.

Here, logic is first digit^second digit + third digit^fourth digit

so,

4²+3¹=19

Similarly: 5¹ + 3²= 14

Hence, option A is the correct answer.

Let the present ages of Aman and Ankit be ‘2x’ and ‘x’ respectively.

Therefore, 2x + x = 72

3x = 72
 

x = 24

Now, Aman’s age after 6 years will be: 2 × 24 + 6 = 54.

Hence, the correct option is D.

Arranging words in the order which they appear in dictionary:

iv. Neither

iii. Neutral

i. Next

ii. Noisy

Hence, the correct option is D.

P is the mother of K.
K is the sister of D.
D is the father of J.
Therefore, J is the nephew or niece of K and P is the grandmother of J.

Hence, option B is correct.

The above given options are all dance forms except from the festival PONGAL.

Hence D

Days left in May = 31 – 17 = 14

Days in November to count = 21

Thus total number of days from Sam's birthday to Renu’s birthday = 14 + 30 + 31 + 31 + 30 + 31 + 21 = 188

Thus number of odd days = 188/ 7 = 6

As Sam's birthday is on Friday, Renu’s birthday will on Friday + 6 days = Thursday.

Hence, option B is the correct answer.

Here the coded form is the opposite letters in the given word.

If we arrange alphabets in two rows as shown below, the letters are related as follows,

Thus EGO is coded as VTL.

Hence, option C is correct.

North West

Explained in three steps :-

Hence, option B is correct.
