If the second half of the given series is reversed, then what will be the fifth term to the left of the ninth term from the right? 9$YX8N6OLBUJZT@1QFD%

• T

• O

• 6

• Q

Answer explanation

Reversing the second half of the series gives: 9YX8N6OLBUJZT@1QFD% -> 9YX8N6OLBUJZT@%DFQ1. The ninth term from the right is 'Q', and the fifth term to the left of 'Q' is 'O', making 'O' the correct answer.

If in a certain code language, CLOUD is written as GTRKF then which word would be written as SIGHT?

In the following question below are given three statements followed by three conclusions. Taking the given statements to be true even if they seem to be at variance from commonly known facts, read all the conclusions and then decide which of the given conclusion logically follows the given statements. Statements: I. Some Bike are White. II. All White are Brown. III. No Brown is a Book. Conclusions: I. Some Bike are Brown. II. Some Book being Bike is a possibility. III. Some White are Book.

• Only I follows

• Only II follows

• Both I and II follow

• Neither II nor III follows

Answer explanation

From the statements, we know some Bikes are White and all Whites are Brown, so some Bikes must be Brown (I follows). Since no Brown is a Book, some Book being Bike is possible (II follows). Thus, both I and II follow.

In the given diagram, Set U is the universal set and Set L, M and N represent students studying History, Geography and Language, respectively. What is the total number of students studying History and Geography but NOT Language?

• 2

• 12

• 5

• 7

Answer explanation

To find students studying History and Geography but not Language, we look for the intersection of sets L and M, excluding those in set N. The diagram shows 2 students fit this criteria, making the correct answer 2.

In the following question, select the related letters / numbers from the given alternatives. H20 : K26 : : P36 : ?

• S42

• T48

• S21

• T42

Answer explanation

The pattern shows that the first letter corresponds to its position in the alphabet (H=8, K=11) and the second number is the letter's position multiplied by 3 (20=8*2.5, 26=11*2.36). Following this, P=16 leads to T=20 and 36=16*2.25, giving T48.

In a certain language “FIVE” can be coded as “5940”, then how will “NINE” be written in that code language?

• 8800

• 8820

• 7980

• 8850

Answer explanation

In the code, each letter corresponds to its position in the alphabet multiplied by 10. For 'NINE': N(14) -> 140, I(9) -> 90, N(14) -> 140, E(5) -> 50. Adding these gives 140 + 90 + 140 + 50 = 4200. The final code is 8820.
