By Using Empurical Formulae;

●Mode=3Median-2Mean

Here,

Median=28 And

Mean=27.5

So putting these value in the formulae

Mode=(3×28)-(2×27.5)

        =84-55

        =29 Ans

Hence mode of the following distribution is 29.

Correct option is (c) 29.0

Correct option is (B) 8

Correct option is (3) 24

Correct option is (C) 14 cm

Correct option is (4) 29 / 343

Correct option is (A) 10

(2) 1/2 of the area of original square 

Correct option is (1) 70

Correct option is (2) 10cm

(3) 27.25

(3.5)³ - (2.5)³ = 27.25

Correct option is (d) 8

Correct option is (2) 27

(1) Mahatma Gandhi

(3) 14  

Number of neutrons = 27 – 13 = 14

(2) spindle shaped, unbranched, unstriaged, uninucleate and involuntary 

Involuntary, unstriated, spindle shaped, smooth, uninucleated.

 (2) during night 

Root pressure is effective way transporting water in xylem during night.

Correct option is (d) John Kay

Correct option is (C) Rare

Correct option is (D) Spoil

(C) Conspiracy

1)  Correct option is (4) 4

2) Correct option is (3) 3

1. (1) A’s income is more than B’s / (4) All are right

A + B > C + D ……(i) 

A + C = B + D ……(ii) 

A = B + D / 2 , so from (ii) we get C = B + D / 2 = A 

Substituting A and C in (i) we get B > D 

So, B > C = A and B > D and B > A 

B > A = C > D. here A’s income is less than B 

If option (1) is false then option(4) must be false

2. (2) B

A + B > C + D ……(i) 

A + C = B + D ……(ii) 

A = B + D / 2 , so from (ii) we get C = B + D / 2 = A 

Substituting A and C in (i) we get B > D 

So, B > C = A and B > D and B > A 

B > A = C > D. B’s income is the highest.

Correct option is (1)

Figure 1 satisfies given condition

Correct option is (2) 6, 2

(4) 9 : 49 1/11

To be together between 9 and 10 o’clock, the minute hand has to gain 45 min spaces 55 min spaces gained in 60 min

45 min spaces are gained in ( 60/55 x 45) min = 49 1/11 min

So answer is 9 : 49 1/11

Correct option is (4) 10 

1. 2) 7

2. 2) 9

3. 2) 5

4. 1) 6

5. 1) 9

D = 7, Q = 4, N = 1, A = 9, T = 5, M = 6

1. (2) AD

If Gita is not sick, means she is careless.

2. (4) None

Raman does not eat hamburgers, means he does not get a swollen nose.

3. (4) BD

If they are not hostile by nature means they have no confidence in the management.

4. (4) None of these

None of the given options relates logically to the given statements.

5. (1) AB

As all irresponsible parents do not shout, it follows that the children read.

1. (4) 5

From statement (a) and (b) Two members are to be selected, 

Of the remaining seven 

To maximize the size of the team we would choose S 

U and W are included in the team(statement (c)). 

We cannot include K or L because we would then have to leave out N and U(from statement (e) and (f))

2. (4) only 4

If ‘K’ is included ‘L’ has to be included (statement(d)). 

If ‘L’ is choose neither N nor U can be chosen(statement(e & f)). 

S, W are also not included because S, U, W have to be always together(statement(c)). 

Hence, one of P or R would be selected (statement(a)) 

And one of M or Q would be selected (statement(b)).

3. (1) 6

If a team includes N, it cannot include ‘L’ and therefore not even ‘K’ (statement (e) and (d)). 

According to the statement (a), one of P or R or S has to be included. 

According to the statement(b) one of M or Q has to be selected. 

So following cases are possible: 

PQN, RQN, PMN, RMN 

If ‘S’ is selected 

SUWMN, SUWQN 

These are the only possible cases 

Thus, in all 4 + 2 = 6 ways

4. (1) L

From the statement (a) and (b)

One of P, R, S and one of M, Q are to be selected. 

But from statement(d) K, L are always together. 

Thus, L cannot be included in a team of 3 members

5. (3) M

From statement (a) one of P, R, S has to be selected. To make a team of 5. S will be chosen(which leaves out P and R) 

If ’S’ is chosen, ‘U’ has to be chosen (statement(c)) 

If ’U’ is chosen, ‘L’ has to be chosen (statement(c)) 

K cannot be chosen(statement(d)) and from statement(b); one of M or Q has to be chosen
