• The earliest kind of print technology was developed in China, Japan and Korea. This was a system of hand printing.
• From AD 594 onwards, books in China were printed by rubbing paper – also invented there – against the inked surface of woodblocks.
• As both sides of the thin, porous sheet could not be printed, the traditional Chinese ‘accordion book’ was folded and stitched at the side.
• Superbly skilled craftsmen could duplicate, with remarkable accuracy, the beauty of calligraphy.
• The imperial state in China was, for a very long time, the major producer of printed material. China possessed a huge bureaucratic system which recruited its personnel through civil service examinations.

The logic follows here is:-

From The Statement

Parrot is a bird, but 'parrot' is called 'rat'. So 'rat' is a bird.

Hence "rat" is the correct answer.

The logic follows here is:

Middle number = square root of first number + third number.

Row-wise operation :

(25, 41, 36)

middle number = 41

= √25 + 36

= 5 + 36

= 41

(49, 45, 38)

middle number = 45

= √49 + 38

= 7 + 38

= 45

Similarly

(36, ?, 62)

middle number = ?

= √36 + 62

= 6 + 62

= 68

Hence, the correct answer is "68"

Additional Information

The most common pattern asked in exams are based on:

• It could be the sum of two numbers divided by a constant
• It could be the average of numbers.
• It could be in the form of alphabets, where alphabets are increased by constant or increased by the square of numbers or increased by prime numbers.
• It could be the difference of product of two diametrically opposite numbers.
• It could be the difference in the sum of adjacent numbers.
• The difference of the numbers could be in the patterns 13 ± 1, 23 ± 1,  and so on.
• The difference of the numbers could be in the patterns 12 ± 1, 22 ± 1, and so on.
• Numbers could be 12, 22, 32, and so on or 13, 23, 33, and so on.
• The difference could be prime numbers or the difference could be the square of prime numbers.
• The difference could be in the form of N2 ± N or N3 ± N.
• The difference could be in the form of ×N + N or ×2 + 1, ×2 + 2, ×2 + 3, and so on.
• The difference could be in the form of ×2 ± 1 alternatively.
• Numbers could be ×1, ×2, ×3, and so on. 

The logic followed is:

Therefore, the number of students in the group are 20 + 30 + 70 = 120

The number of students = 120

Hence, the correct answer is "120".

P, Q, R, S, T, V, W, and Z are sitting around a circle facing at the centre not necessarily in this same order.

i) T is second to the right of R who is third to the right of P.

Mistake Points

Who is used for the second person in a connecting statement.

For example: 

T is second to the right of R who is third to the right of P.

Here, who is used for R and not for T.

ii) S is second to the left of P and fourth to the right of Q.

iii) V who is not an immediate neighbour of P. (This means V cannot sit immediate left or right of P).

iv) Z is third to the right of V 

Thus we can see Z sit second to the right of T.

Hence, the correct answer is "Option 2".

TCP/IP (Transmission Control Protocol/ Internet Protocol) is the basic communication language or protocol of the Internet. It can also be used as a communication protocol in a private network (either an intranet or an extranet).

Mrs. Sharma makes her assessment useful and interesting by using various ways to collect the information. Each way provides a different piece of information or same information with some additional inputs. For example, a written question paper gives us the idea of the person's knowledge, an oral assessment gives us an idea of the person's verbal ability and articulation, and activities may prove useful in testing child's ability to apply the knowledge practically. Activities also make assessment interesting for children.

The cause of Rohit's poor performance can be either physical problems, family disturbances or his maturation process.
Rohit may not be physically fit or may be suffering from some physical ailment, which might be affecting his studies and resulting in poor performance.
There may be some disturbances at home, which may be affecting his studies. A construction work at home or a fight amongst elders could be the reason behind his recent performance.
The mental capabilities of Rohit are maturing but maybe not up to the level that is required to understand the concepts taught in the class. Thus, he might be performing poorly.
Apart from this, the teacher might lack the required knowledge of modern educational and psychological theories. This can lead to students' poor academic performance. Several other factors also lead to poor academic achievement, such as social factors, economic factors and political conditions.

if f(x) is an odd function

So, f(−x)=−f(x)

F(−x)=cos(f(−x))

=cos(−f(x))

=cos(f(x))

=F(x)

So cos(f(x)) is an even function

So, f(x) and g(x) is an even function

Clearly , (M−1)⁻¹ = (M⁻¹)¹ is not true.

Since AB is fixed and AC is perpendicular to BC. So, locus of C is a circle whose diameter is AB. So, family of circles passing through AB is 
x² + y² - 6x - 8y + 21+λ(x + y -5) = 0
⇒x² + y² - (6 - λ)x - (8 - λ)y + 21- 5λ = 0

Since AB is diameter so centre must lie on AB

∴ Locus is x² + y² - 4x - 6y + 11 = 0.

All possible three number multiplications originate from the following triads:
1,1,30
1,2,15
1,3,10
1,5,6
2,3,5
First one can have 3!/2! = 3 ways and the remaining four triads can have 3! combinations
total combinations = 3 + 4*3! = 27

Lev Vygotsky is a Soviet psychologist who did plenty of research on children and came up with the sociocultural theory of cognitive development. His theory was based on the effects of social interactions on a child's cognitive development.
