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

Expression = 6 : 42 : : 7 : ?

The pattern followed is = n : n² + n

Eg = 6 : 6² + 6 = 6 : 42

Similarly, 7² + 7 = 49 + 7 = 56

Expression = ABCD : ZYXW : : EFGH : ?

The pattern followed is that every letter is opposite to each other.

Thus, EFGH : VUTS

Expression = 12 : 72 : : 8 : ?

The pattern followed is =

Expression = 2 : 32 :: 3 : ?

The pattern followed is = n : n⁵

Eg = 2 : 2⁵ = 2 : 3²

Similarly, 3⁵ = 243

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.

Expression: 132 & 3 # 10 @ 20 % 2 = ?

=> Ans - (d)

Expression: 38 x 2 - 6 + 19 ÷ 35 = ?

≡ 38 ÷ 2 × 6 − 19 + 35

= (38 × 3) + 16

= 114 + 16 = 130

=> Ans - (a)

Expression: 187 B 17 C 4 A 7 D 17 = ?

≡ 187 ÷ 17 × 4 + 7 − 17

= (11 × 4) − 10

= 44 − 10 = 34

=> Ans - (d)

Expression: 315&3#9@4%6 = ?

≡ 315 ÷ 3 − 9 + 4 × 6

= (315​/3) + (−9) + (4 × 6)

= 105 − 9 + 24 = 120

=> Ans - (a)

Expression: 26 + 400 x 20 - 21 ÷ 12 = ?

≡ 26 − 400 ÷ 20 + 21 × 12

= (26) − (400​/20) + (21 × 12)

= 26 - 20 + 252 = 258

=> Ans - (a)

Expression: 154 x 11 + 78 - 5 ÷ 45 = ?

≡ 154 ÷ 11 − 78 × 5 + 45

= (154​/11) + (−390) + 45

= 14 + 45 − 390 = −331

=> Ans - (a)

If "-" stands for division, "+" stands for multiplication, "÷" stands for subtraction and "×" stands for addition,

(A) 8 + 6 − 3 ÷ 4 × 6 = 16

≡ 8 × 6 ÷ 3 − 4 + 6 = 16

L.H.S. = 48/3 ​+ 2 = 16 + 2 = 18 ≠ R.H.S.

(B) 16 − 4 + 4 ÷ 2 × 6 = 20

≡ 16 ÷ 4 × 4 − 2 + 6 = 20

L.H.S. = (4 × 4) + 4 = 16 + 4 = 20 = R.H.S.

=> Ans - (b)

In the first column, the number at the top is obtained by adding the other two.

Eg = 39 + 275 = 314

and 102 + 103 = 205

Similarly, 34 + x = 111

=> x = 111 - 34 = 77

=> Ans - (c)

In each column, the last number is obtained by multiplying the other two.

Eg: 13 × 17 = 221

and 17 × 19 = 323

Similarly, 7 × 23 = 161

=> Ans - (d)

The pattern followed is that in the first row, the number in the middle is obtained by adding the other two and dividing the result by 3.

=> x = 120 − 55 = 65

=> Ans - (d)

In each row, the first two numbers are added and twice the difference is subtracted to obtained the third number.

Eg: 24 + 20 - 2(24 - 20) = 44 - 8 = 36

and 15 + 11 - 2(15 - 11) = 26 - 8 = 18

Similarly, 55 + 40 − 2(55 − 40) = 95 − 30 = 65

=> Ans - (b)

In each column, the number at the end is obtained by multiplying the other three numbers.

Eg: 3 × 4 × 3 = 36

and 5 × 6 × 7 = 210

Similarly, 9 × x × 12 = 36

=> x = 36/108 ​= 1/3

=> Ans - (c)

The pattern followed is for a @ b = (a − b) × 2

Eg = 9 @ 3 = (9 − 3) × 2 = 6 × 2 = 12

and 15 @ 4 = (15 − 4) × 2 = 11 × 2 = 22

and 16 @ 14 = (16 − 14) × 2 = 2 × 2 = 4

Similarly, 6 @ 2 = (6 − 2) × 2 = 4 × 2 = 8

=> Ans - (d)

Both teachers and graduates are part of human beings.

Also, some of the graduates can be teachers also and some maybe not.

=> The above relation is correctly depicted by:

Set of letters that represents Cricketers who are also Cartoonists = G + H

Both peas and kidney beans are part of legumes. Also peas and kidney beans are different.

Thus, the venn diagram the best describes their relation is:

Bio products can include food because this term is also related to agriculture. But all bio products are not food because it also includes making of fossil fuels, papers etc. We can also make different type of poison by using various bio products.
So, some bio products can be poison and some can be food.
