Practice Test: Logical Reasoning - 15 - Question 1
Save

In each of the following questions, select the related word/letters/number from the given alternatives.
BLOCKED : YOLXPVW : ? : OZFMMXS

Detailed Solution: Question 1

Expression = BLOCKED : YOLXPVW

The pattern followed is that each letter is replaced by the letter at its position, when the alphabets are reversed, i.e. first is replaced by last, second by second last and so on.

Thus, L -> O
A -> Z
U -> F
N -> M
N -> M
C -> X
H -> S

\therefore∴ LAUNNCH : OZFMMXS

Practice Test: Logical Reasoning - 15 - Question 6
Save

If "P" denotes "multiplied by", "R" denotes "subtracted from", "S" denotes "added to" and "Q" denotes "divided by", then which of the following equation is true?

Detailed Solution: Question 6

1) 18 R 60 Q 15 S 2 = 8

On changing symbols

→ 18 - 60 ÷ 15 + 2 = 8

→ 18 - 4 + 2

12 ≠ 8

2) 15 S 16 Q 2 P 4 = 47

On changing symbols

→ 15 + 16 ÷ 2 × 4 = 47

→ 15 + 8 × 4

→ 15 + 32

→ 47 = 47

3) 3 P 5 R 18 Q 3 = 6

On changing symbols

→ 3 × 5 - 18 ÷ 3 = 6

→ 15 - 6 = 6

9 ≠ 6

4) 15 S 28 Q 4 P 2 = 27

On changing symbols

→ 15 + 28 ÷ 4 × 2 = 27

→ 15 + 14 = 27

29 ≠ 27

Hence, ‘15 S 16 Q 2 P 4 = 47’ is the correct equation.
