→ BD = X ⇒ 24 = 24
Hence, “X” is the correct answer.

QUESTION: 5

Select the related word from the given alternatives.
Copper : ductile ∷ chalk : ?

Solution:

→ Ductility is the most important physical property of copper. Ductility of a material is its ability to deform when a force is applied upon it.
→ Brittleness is the physical property of chalk. Brittleness is exactly an opposite property of ductility as it is the ability of a material to break without first undergoing any kind of deformation.
→ In Brittleness, material breaks down without any deformation. Chalk material having such physical property therefore, chalk is related to brittle.

QUESTION: 17

Jais and his father has an age difference of 35 years now. After 5 years, the sum of their age is 125. What will be the age of Jais and his father after 12 years from now?

Solution:

Let the present age of Jais be X years and the age of his father be Y years.
Presently, Jais and his father has an age difference of 35 years.
→ Y – X = 35. ----------- (1)
After 5 years, the sum of their ages will be 125.
→ (X + 5) + (Y + 5) = 125
→ X + Y + 10 =125
→ Y + X = 115. ----------- (2)
Y – X + Y + X = 35 + 115
→ 2Y = 150
→ Y = 75.
Similarly, X = Y – 35 = 75 – 35 = 40.
After 12 years, Jais age is 52 (40 + 12) years and his father’s age will be 87 (75 + 12) years.
Hence, the correct answer is 52, 87.

Select the correct combination of mathematical signs to replace * signs and to balance the following to form an equation:
( √121 * 9) * (5 * 4) * 1

Solution:

Let us first simplify the given equation:
( √121 * 9) * 5 * 4 * 1→ (11 * 9) *  5 * 4 * 1
Now we will check each option one by one:
(11 * 9) * 5 * 4 * 1→ (11 + 9) ÷ (5 × 4) = 20 ÷ (5 × 4)
Now if we take 20 ÷ (5 × 4) = 20 ÷ 20 = 1 True, thus this option can be correct.
(√121 * 9) * 5 * 4 * 1→ (11 = 9) + 5 × 4 ÷ 1 False, thus this option is wrong.
(11 * 9) * 5 * 4 * 1→ (11 – 9) × 5 + 4 = 1 False, thus this option is wrong.
(11 * 9) * 5 * 4 * 1→ (11 – 9) + 5 × 4 = 1False, thus this option is wrong.Hence possible answer is + ÷ × =.

QUESTION: 20

Eight people A, B, C, D, E, F, G and H are sitting around the circular table facing towards center of it. A and B are sitting opposite to each other. F is sitting immediate right of A. There is at least one person between B and H and H is not the neighbor of F. C and D are sitting opposite to each other and none of them is sitting adjacent to F.G is not sitting opposite to F.
Question: Who is sitting opposite to H?

Solution:

People are sitting around the circular table in the following way- All the eight positions are named from1 to 8.
Now it is told that, A and B are sitting opposite to each other and F is sitting immediate right of A.
So our arrangement will look like- Now There is at least one person between B and H and H is not the neighbor of F so H can sit at position 3, 4, or 6.
Now it is told that neither C or D is adjacent to F and C and D are opposite to each other,
Hence our arrangement will look like So H has to take position 3.
Now it is told that G is not opposite to F then E will be opposite to F.
Then our final arrangement will look like- Hence G is seating opposite to H.

QUESTION: 24

Directions: In the question below are three statements followed by three conclusions numbered I, II and III. You have to take the three given statement to be true even if they seem to be at variance from commonly known facts and then decide which of the given conclusion logically follows from the three given statements, disregarding commonly known facts.
Statements:
Some rivers are hills.
No hills are taxi.
All taxi are buses.
Conclusions:
I. Some buses are rivers.
II. Some rivers are definitely not taxi.
III. No bus is river.

Solution:

From the statements, the least possible Venn diagram can be drawn as below: Conclusions:
I. Some buses are rivers → Its possible but not definitely true, hence false.
II. Some rivers are definitely not taxis →Some rivers are hills and no hill is taxi, so that much portion of river which is hill will never be taxi. Hence true. III. No bus is river → Its possible but not definitely true.
Hence, only conclusion II follows.
But, since I and III make complementary pair hence, either I or III also follow.
So, conclusion II and either I or III follow.
Therefore, none of these is the correct option as there is no such option like conclusion II and either I or III follows.

QUESTION: 25

In the following question, two statements are given each followed by two conclusions I and II. You have to consider the statements to be true even if they seem to be at variance from commonly known facts. You have to decide which of the given conclusions, if any, follows from the given statements.
Statement:
(I) Women generally prefer window shopping.
(II) Males generally are not fond of window shopping and they feel that it is a sheer waste of time.
Conclusions:
(I) Shopping behavior is different for males and females.
(II) If males go for window shopping, they don't utilize much time in selecting a product.

Solution:

As in statement it is mentioned that Women prefer Window shopping and Males does not prefer. Hence, conclusion (I) follows as shopping behaviour is different for males and female.
But conclusion (II) does not follow as in statement nothing is mentioned if males go for windows shopping, they don’t utilize much time in selecting a product.
Hence, only conclusion I follows. Use Code STAYHOME200 and get INR 200 additional OFF Use Coupon Code
