The least possible Venn diagram for the given statements is as follows,

Conclusions:
I. No book is a diary → False (It is possible but not definite, as there is no direct relation between book and diary Therefore it is possible but not definite).
II. All diaries are books → False (It is possible but not definite,as there is no direct relation between book and diary Therefore it is possible but not definite)
III. No diary is a novel → True (No novel is a diary, imply that no diary is a novel)
Therefore, the correct answer is only conclusion III follows.

We can count the rectangles as follows,

Therefore, there are “24” rectangles in the given figure.

Hence, the correct option is (D).

The pattern that is being followed here is as follows,
729 → 7 + 2 + 9 = 182 = 324
Similarly, 512 can be written as,
512 → 5 + 1 + 2 = 82 = 64

As

Similarly,

Thus, EUTX is related to HPWS.

Brands of Deodorant - AXE, Degree, Envy, Fogg, Nivea, Old spice and Park Avenue.
1) There is only one box above box of Degree.
2) The box of Park Avenue is the bottom most box.
3) The number of boxes above the box of Fogg is equal to number of boxes below the box of Envy.

4) The box of AXE is above box of Old spice, which is above box of Envy. So, Fogg and Envy must be in box 3 and box 5 respectively. AXE and Old spice must be in box 1 and box 4 respectively. Also, Nivea must be in box 6.

Four boxes are above box of Envy.

Brands of Deodorant - AXE, Degree, Envy, Fogg, Nivea, Old spice and Park Avenue.
1) There is only one box above box of Degree.
2) The box of Park Avenue is the bottom most box.
3) The number of boxes above the box of Fogg is equal to number of boxes below the box of Envy.

4) The box of AXE is above box of Old spice, which is above box of Envy. So, Fogg and Envy must be in box 3 and box 5 respectively. AXE and Old spice must be in box 1 and box 4 respectively. Also, Nivea must be in box 6.

AXE is in topmost box.

Best possible figure according to the given information:


Clearly, M is the mother of P.

We know,

Given,
W, V, S, N, ?, X, M
The pattern followed here is,

Therefore, the correct answer is G.

From root, stem will emerge.
From primary stem, leaf will emerge.
From leaf, flower will emerge.
From flower, fruit will emerge.
Hence, the correct arrangement is Root, Stem, Leaf, Flower, and Fruit.
Thus, 4, 3, 1, 5, 2 is the correct arrangement.

The pattern followed here is,
O + 1 = P
P + 2 = R
R + 3 = U
U + 4 = Y
Y + 5 = D

The logic followed here is :-
TONGUE : PUHOFV

Similarly,
MASTER : ?

Hence, the correct answer is "BNUTSF".

The logic followed here is:
Vowels –  Positional value - 2
Consonants – Reverse letter in the alphabet

CHOIR is written as XSMGI,

DROPS is written as WIMKH,

Similarly,

Hence,  HOLDER is coded as SMOWCI.

The correct mirror image of the given figure when the mirror is placed at XY:

Hence, "option 1" is the correct answer.

Six Students: A, B, C, D, E and F.
1) C is sitting second to the left of B. 

2) A is sitting immediate left of C. 

3) F is sitting second to the left of A.

4) B is an immediate neighbour of both F and E.

So, the final arrangement is;

Therefore, D is the immediate neighbour of A and F 
Hence, the correct answer is "D".

The pattern followed in the given series is:
The difference of the difference between the term is ÷2 of the previous difference.

Hence, the correct answer is "option (1)".

As per the given question:

• L is 20 km south of B. A is 10 km west of B. J is 25 km east of L.
  
• If R is 31 km east of B. J is 28 km south of T. 
  

Now,
Distance between RT is calculated by using Pythagoras theorem:
→ (RT)² = (TC)² + (CR)² 
→ (RT)² = (8)² + (6)² 
→ (RT)² = 64 + 36
→ (RT)² = 100
→ RT = 10 km
Clearly, T is 10 km far from R and J is in 'South East' direction from A
Hence, the correct answer is "10 km, South-East".

The logic followed here is:

Hence, 'Option 4' is the odd one.

The logic followed here is:
Here, we need to apply the combination of signs to get the correct equation.
Given: 93 * 65 * 3 * 56 * 14 * 146
First we will check options one by one as below:
1) ×, +, -, ÷, =  
⇒ 93 × 65 + 3 - 56 ÷ 14 = 146
⇒ 93 × 65 + 3 - 4 = 146
⇒ 6045 + 3 - 4 = 146
⇒ 6048 - 4 = 46
⇒ 6044 = 146, is not possible. This is not true.
2) +, -, ÷, ×, =
⇒ 93 + 65 - 3 ÷ 56 × 14 = 146
⇒ 93 + 65 - 0.053 × 14 = 146 
⇒ 93 + 65 - 0.75 = 146
⇒ 158 - 0.75 = 1436
⇒ 157.25 = 146, is not possible. This is not true.
3) -, +, ×, ÷, =
⇒ 93 - 65 + 3 × 56 ÷ 14 = 146
⇒ 93 - 65 + 3 × 4 = 146
⇒ 93 - 65 + 12 = 146
⇒ 105 - 65 = 146
⇒ 40 = 146, is not possible. This is not true.
4) +, -, ×, ÷, =
⇒ 93 + 65 - 3 × 56 ÷ 14 = 146
⇒ 93 + 65 - 3 × 4 = 146 
⇒ 93 + 65 - 12 = 146
⇒ 158 - 12 = 146
⇒ 146 = 146, is possible. This is true.
Hence, the combination of signs ' +, -, ×, ÷, =' is used to get correct balanced equation.

Emergency helpline numbers is as follows;

102 is the emergency number of Ambulance not for the woman helpline.
Hence, "102 - Women Helpline" is the odd one out and hence it is considered as the correct answer.

The logic followed here is :-
Given series : A U R R G H R S W C G I O P D S Q T  
Total 18 letters are there in given series.
First half of given letters are : A U R R G H R S W
After reversing the first half of given series the series is as follows : W S R H G R R U A C G I O P D S Q T
The letter 8th from right end is : W S R H G R R U A C G I O P D S Q T
⇒ The letter which is third to left of letter which eight from right end of series formed is : W S R H G R R U A C G I O P D S Q T
Hence, the correct answer is "U".

By using the symbols in the table given below, we can draw the following family tree:

Based on the following data, the family tree diagram can be drawn as shown below,

Hence, the boy related to Ram is "SON".

Given:
1) length of Mango Tree & Coconut Tree are same:
⇒ Coconut Tree = Mango Tree
2) Banana tree is smaller than palm tree: 
⇒ Banana Tree < Palm Tree ......  Eq (1)        
3) Guava tree is shorter than the Banana tree but taller than the Mango tree:
⇒ Mango Tree < Guava Tree < Banana Tree ...........   Eq (2)
Now from Equation (1) & Equation (2).
Coconut Tree = Mango Tree < Guava Tree < Banana Tree < Palm Tree 
We can see in the above equation that Palm tree is the tallest one.
Hence the correct answer is "Palm".

Given:
Principal = Rs. 10000,
Rate = 40% per annum
Compound interest earned on 3rd year = Amount received after 3 years – Amount received after 2 years.
In case of compound interest:

Where,
P = Principal, R = rate of interest and T = Time
And
CI = Amount – Principal
Applying the formula:
Amount received after 2 years = 10000 × ((1)+(40/100))²
= Rs. 19600
And
Amount received after 3 years = 10000 × ((1)+(40/100))³
= Rs. 27440
∴ Interest for the 3rd year = 27440 – 19600 
= Rs. 7840.

Amount of water in the mixture = 15L
⇒ Milk = 85 L
On adding the milk to make the concentration of milk 87.5%, the quantity of the milk remains the same,
⇒ 12.5% Water = 15 L
⇒ 100% = 120 L
⇒ Out of 120 L, the concentration of water is 15L
⇒ Quantity of milk = 105 L
∴ Quantity added = 105 – 85 = 20 L.

Given:
Internal diameter of hollow sphere (d) = 4 cm
Internal radius of hollow sphere (r) = 4/2 = 2 cm
External diameter of hollow sphere (D) = 8 cm
External radius of hollow sphere (R) = 8/2 = 4 cm
As we know,
Volume of the Hollow sphere =

Diameter of the cone (d₁) = 8 cm
Radius of the cone (r₁) = 8/2 = 4 cm
Let the height of the cone be ℎ cm
Volume of the cone = 

Volume of the cone = Volume of the hollow sphere

So, the height of the cone is 14 cm.

Let the son's present age be x years.
Then, man's present age = (x+24) years
So, according to the question,

The possible combinations are (5,3,2)(2,4,4),(3,3,4),(2,2,6),(7,2,1), (8,1,1)
Product of the combinations 
⇒ 5×3×2 = 30
⇒ 2×4×4 = 32
⇒ 4×3×3 = 36
⇒ 2×2×6 = 24
⇒ 7×2×1 = 14
⇒ 8×1×1 = 8
36 is the maximum product among the combinations.
∴ 36 is the maximum product of (a×b×c).
